The new battery charging algorithms are so effective that they could help batteries charge twice as quick, and help the fuel cells run more efficiently and potentially cut production costs by 25 percent. During test the new algorithms have been able to charge flat batteries in as little as 15 minutes. The team at the Jacobs School of Engineering at UC San Diego are currently sharing a $9.6 million grant from ARPA-E, a research agency within the Department of Energy, with automotive products supplier Bosch and battery manufacturer Cobasys. To help develop the estimation algorithms even further and make them a more viable product for release. A preview of Android 4.3 by Pocketnow suggests huge improvements to battery-life, with the site reporting 25 hours of heavy usage. Other improvements noted were auto-complete for the phone dialer (offered on some carriers now but not a standard part of Android 4.2), new emoticons, and improved camera UI and responsiveness to change in orientation (which is already in the HTC One Google Play edition). As someone who has been lucky enough to spend the last few months testing iOS 5 in various beta stages, it has to be said that the version we’re all currently enjoying has come a long way since the early days. When Apple released the iOS 5 GM not that long ago, I instantly noticed that my iPhone 4’s battery life was lasting roughly half of what it was before. See, it appears that iOS 5’s GM release introduced a bug that causes the Setting Time Zone function to keep the location tracking circuitry running constantly, draining battery power considerably. Interestingly, there appears to be no rhyme or reason as to why some handsets seem to have the issue, with not all iOS 5 installations apparently causing the bug to manifest itself in the same way. Special thanks must go to Jon Honeyball of PC Pro fame for the original idea that got all our testing underway. I have the iphone 4 with ios 5 (not jailbroken) and even with this setting off (which it has been since I noticed the arrow in my status bar right away when I got ios 5) my battery life is literally about half of before.
What seemed to have an effect (still verifying) is turning off sync with wifi and turning off syncing with icloud. I think some of the extra usage is just lighting up the screen every 15 minutes (at least, for my case) when you get a new notification. Not everyone seems to bee affected so don’t miss out on iOS 5 because of a small percentage of user problems.
Nice one, thanks for that.,, after switching it off my battery life is now as it ahould be!!
I disabled it anyway as well as traffic, iads, and diagnostics on my 4S and see if it will help. Meanwhile, if someone has a suggestion on my wife’s phone issue, I would appreciate it. As some above already mentioned, the screen lighting up with every notification, I use boxcar for FB, email and Twitter and wouldn’t miss it for the world, drais a lot of power too.
I noticed drastic improvements in bat life on the 5.0 software, but, sometimes the location hangs, and that drops 2-3 hours of bat life. I feel battery life is the next frontier in Nanotelecomputers; in that regard if Apple could make the 4Sx or the 5 a 1mm (or 2) thicker and few ounces heavier but lasted 12 hours of abuse use they will make the, at least in my scale, the first superphone (or Super Nanotelecomputer). The only thing which so far worked splendidly was switching off the phone plus the location – just with WiFi the battery is fine. Did anyone also have this mistery in loosing a few battery percent thought connected to power?
But I have to say: Sorry Apple, but if you want to sell a smartphone for 660€, this just don’t have to happen!!! Thanks for your post have tried that made no difference, battery still running low very quick.
Also noticed the iphone 4S heating up, its quite warm to the touch if not hot surely thats not normal. It is standard for ALL recharable batteries, at least once a full cycle of charge and drain, and for better lifetime once a month. I have an iphone 4s and changing the time zone setting made no difference but when I turned off the compass calibration it seemed to make a difference. I turned off push for email, ALL notifications, including vibrate, and most sounds, with the exception of the ringtone and the `swoosh’ for sent email. I checked the Time Zone location thing as instructed here and yes, the status bar icon disappeared. Until somebody figures out how to build a car that doesn’t rely on a battery, dead batteries will remain the bane of all motorists. We used to have new (GM) vehicles come in, especially during the winter, with the batteries next to dead. Batteries are probably one of the things that differentiate the novice from the experienced driver.
This may sound selfish, but I NEVER carry jumper cables, due to the potential for killing my alternator. No Acid, you never lose the acid potency just the water vapor, so adding acid just creates more gases.
That’s why, if you use a smart charger, you may wonder why it takes so long with the charge current changing radically.
With all the hoopla around the new iPad getting a little bit toastier than its predecessor, Dr. Is this an iOS software flaw akin to a “bug” in cellular signal levels on the iPhone 4 (later fixed with a software update)?
I measured the power actually drawn by the AC adapter and found that the new iPad continues to charge for up to 1 hour after it claims to reach 100 percent.This affects the battery run time if you stop charging when it says 100% percent.
Notably, iLounge found unusual, non-linear reported battery drain during our numerous battery tests, with the third-generation iPad sometimes reporting a battery loss of just two percent over the first hour of testing, then averaging 10% of loss each hour afterwards while performing the same tasks. According to his LinkedIn profile, Soneira is president of DisplayMate Technologies Corporation of Amherst, New Hampshire, a company specializing in scrutinizing computer and mobile displays of all flavors.

DisplayMate compared a 2,048-by-1,536 pixel resolution Retina display to those found on other popular smartphones and tablets. I know what you mean, but keep in mind that if you sold your iPad2 before the iPad 3 was released, you still got more money for it.
Bring your idea to market faster with Shark FX, the new standard in Conceptual Computer Aided Design (CCAD). Shark FX is a full featured 2D & 3D digital design solution that provides solutions that address versatile modeling practices, photorealistic rendering, animation, and precision drafting capabilities all within one seamlessly integrated package. Use our photo realistic rendering and animation tools to help communicate and sell your ideas to others. As a reminder, I use my phones quite a bit more than the average user, so my battery life is expectedly lower than what most should expect to get. Switching it off may mean that your iPhone will no longer set its own time zone when you travel, but that’s a small price to pay for having your iPhone last more than 12 hours on a full charge. There’s no need to cripple such essential functionality, and it appears that the Setting Time Zone option is the one that causes the hit on battery life. The screenshots below, taken using my own iPhone 4S before and after the change, tell their own story. I could even quit the maps app but if I had traffic turned on it would stay active in the status bar. I was wondering why my fairly new iPad 2 was running low on juice much quicker than before sine the ios5 update. Since I have wrote the first time in this blog, some 50min ago, my battery power dropped down 9%! I noticed higher than normal battery drain, went into settings & locations services to investigate and noticed time zone setting constantly using location services. I did a hard reboot, then killed all the apps running, also turned off the real time local weather. To fix this issue you run the phone completely down until it turns off, then recharge it completely without interruption.
While we recently discussed how to choose the right replacement battery for your car, properly maintaining and charging your car’s battery will prevent battery failures and keep you from unnecessarily having to replace your battery. Charging them for an entire weekend couldn’t bring them back, so the batteries got sent to the battery recycle bin and new ones were installed under warranty.
If your voltage went from 9 to 12.74, it is taking a charge but it may not be able to store it. Sometimes dropping the battery on a cushioned floor (from a few inches above it) will jar loose some of the built-up deposits between the plates.
In NY state, battery acid is like compression fittings, the sales person can sell them to you if you ask for them, but if you tell them you are using the acid to refill a battery or the compression fitting to repair a brake line, the salesperson cannot, by law, sell them to you without assuming partial liability.
I found over the years that engines that were maintained so they started quickly with minimum cranking had the longest lasting batteries. The article says other devices do this as well, but stops short of specifying whether Soniera was referring to other Apple devices or those from other vendors. Shark FX is the complete solution for creating concept through production digital prototypes.
Shark FX not only delivers unprecedented usability, but provides an uncompromised, extensive set of 2D & 3D design tools. All modeling operations remember how they were constructed through a feature tree and geometric associativity. Drag and drop materials, decals, and background environments to turn your digital prototypes into stunning photo realistic renderings.
With Shark FX, your 2D drawings are just a mouse click away using our innovative Model to Sheet tools. On Android 4.3, without changing my usage habits, I was surprised to see the phone last all day, all evening, and still had charge enough to get me to work the next morning.
On the other hand I really like iOS 5 and the ability to sync calendar, contacts and reminders between devices. If you leave the phone connected and take it on the next day i often had the problem the battery was down to 97% or even less.
What I find interesting is that when checking usage before turning Setting Time Zone Off, it was usually close to the equivalent of the standby time since the last charge – maybe 20 minutes difference. Turned it off and battery life has markedly improved (though I still think a little worse than with iOS 4 (when using iBooks anyways). One of the major causes of battery failure is improper maintenance of the battery itself or the attached terminals and cables. Then we got a new Divisional Service Manager who told us that the Delco batteries with the green (Delco Eye) had a unique acid formula (his words, I never bothered to check for myself) and thus needed some hefty jump starting in order to stir up things inside. A Battery Tender is great at keeping the battery from sulfating and freezing while not in use and greatly increases the life of a battery.
The battery was rally bad after sitting in a car not used in two months, multimeter showed just above 9 volts. Yesterday, he explained how the demanding Retina display and brightness levels affect the iPad’s run time.
All we know is it keeps charging for as much as an hour after the battery gauge hits the 100 percent mark.
Shark FX has been designed, from the ground up, to be intuitive for the casual user as well as the professional engineer. Change a key feature or modify reference geometry to explore different part configurations. Notable tools include numerous spline creation and modification commands, seventeen surface construction methods, blending, chamfering, shelling, stretching, twisting, bending, and foreign part editing tools. I noticed that suddenly the battery drains very fast and even during the night when it wasn’t used at all. Corrosion of the battery posts and the cables that attach to it can reduce the ability of the charging system to re-invigorate the battery and lead to a constantly undercharged battery that could let you down when you least expect it.

I had one of these I pirated from a 70’s Toronado in a 1963 Pontiac four door hardtop for over ten years, and it never did cause a problem, summer or winter. Today, he’s back at it, warning the device keeps charging even when it claims to have been filled.
Use dimensions and constraints to drive 2D profiles which are then used to define extruded, lathed, or swept 3D components.
All surface and solid modeling operations transparently support associativity and a history tree for rapid design modifications.
Twitter and forums on the web over lit up with similar problems, and a few fixes were suggested, mostly to no avail. And yes, using my Iphone while browsing or playing around, I recognize noticeable heat up at it’s backside, too!
I hope this works, as my phone lasted for days before I installed OS5, now it lasts about five hours. Proper cleaning of the terminals and replacement of frayed cables will ensure the charging amps being produced by the alternator or generator are making their way into the battery. If you are storing an RV, boat, motorcycle, lawn tractor or classic car through the winter consider the use of a tender.
It’s a non-serviceable battery but I removed sticker and could then easily pop the cover and check electrolyte level, which was fine on all cells. Not only that, we didn’t notice it when we set the phone down for several hours and it drained down to nothing. For those traditional batteries that still have removable caps, the water level inside should also be periodically checked. I plugged it in and it did not seem to charge, so I rebooted it and got the battery to charge. The battery will not recharge to its full potential unless the plates inside the battery are covered in electrolyte. As the battery charges, the chemical reaction releases water vapor, which will lower the water level in the battery. Now when I plug it in either to the wall charger or the computer, it will be on and working for 5 or 10 minutes then it re-boots on it’s own.
It reads 12.74 volts, which should indicate a pretty much full battery, shouldn’t it? On some sealed batteries, the vapor is reclaimed, while many import car non-sealed batteries use a vent tube that expels vapor and gases safely away from the battery. For recharging a dead battery, there are several different types of battery chargers to consider. These chargers will provide a sufficient jump charge of amps in place of your bad battery, and the charging system should produce enough amps to maintain the electrical system until the battery can be fully recharged.
Jump boxes usually provide between 500 and 1,200 amps of boost for starting, but they are not meant to be used as a charger.
Commercial chargers will recharge a battery quickly at a high amp rate, usually 60 to 100 amps per hour and will have a separate boost switch for jump starting that provides 50 to 250 amps for starting power. Commercial chargers will also have a timer that can be preset to protect the battery from overcharging. Most home-use chargers are medium-duty units that charge your battery at between 5 and 50 amps.
Features may include a small boost charger, timer or automatic shut-off that senses when the battery is approaching full charge and shuts itself off. These smaller battery chargers take longer to complete a recharge, but are less likely to cause damage to your battery over a commercial fast rate unit. When storing a car over several weeks or months, the possibility of the battery discharging while at rest is another concern. Newer vehicles have computers and other power accessories that remain active while the car is at rest, and these electrical items can slowly drain a battery until it no longer has enough cranking amps to start the vehicle. The trickle charger produces a constant small amp charge, usually 2 amps or less, that keeps the battery fully charged while at rest.
The trickle charger can also keep the battery from freezing in extreme cold because the chemical reaction it causes during the recharge process produces a small amount of heat. Some of the 500 milliamp chargers still need to be monitored and disconnected periodically; however, most trickle chargers you see on the market today have an automatic shut-off and turn-on mode that will maintain your battery over extended periods of time without constant checking. Most battery manufacturers recommend that you use a trickle charger to recharge a discharged battery. Because the amp ratings are low, the trickle charger can efficiently bring the battery back up to full charge slowly without causing any excess heat or sulfating caused by chargers with larger amp rates. If you are considering outfitting a garage or storage area for your car, it is recommended that you invest in both a trickle charger and a larger unit with an emergency boost mode to cover all bases.
Known brand names such as Schauer, Exide, Battery Tender, Die Hard and Schumacher may be more expensive, but have been found to be more reliable and longer-lasting than cheaper models.
Brand name units can also be rebuilt, while cheaper units are often bounced off the wall or driven over in anger when they fail. First, make sure both vehicles share the same voltage and either positive or negative grounding before attempting to use jumper cables.
Most (but not all) six-volt systems are positive grounds and most (but not all) 12-volt systems are negative grounds, but check to make sure, especially with British cars. Crossing wires or supplying too much voltage will cause a battery to explode or leave you with two vehicles in need of a jump.
Additionally, after hooking up the vehicle to be charged first, install the positive on the vehicle supplying the juice and the negative to a convenient ground on the block instead of the negative battery terminal. This ensures that, if there is a spark when the last collection is made, it will not be near the battery where gases could ignite.
