Forum Samsung Android Phones Samsung Galaxy S4 Carrier Specific Samsung Galaxy S4 Help & Discussion Sprint Samsung Galaxy S4 S4 will say charging but battery life goes down when screen is on. Zachary Gebis Posts 2 Posts S4 will say charging but battery life goes down when screen is on. Issue: Battery will discharge when the phones screen is on or phone is being used, even if the phone is connected to power and the phone states it is charging.
Changed usb cables, swapped wall chargers, tried different batteries, changed the internal usb port and board.
If I plug my phone into the charger that I have been using for a very long time without issues the phone will say charging (show icon and beep), but as I use it the % of capacity of battery drops.
Strange thing is when one presses *#9900# the option “low battery dump” and “TCP DUMP START” are grayed out by you can still toggle them.

Last Post: 11-02-2015, 11:58 AM My Chromecast was working, but then why did it say 'reconnect me' and then try to connect? I know its not the HD MAXX but I had read that my brand new RAZR HD should be able to easily withstand 10 or more hours of light or even heavy use.
Why should I have to pay 100 dollars more for a phone that is supposed to have 20 hours of battery life?

Posted via Android Central App All I'm saying is the extra hundred dollars would be worth it. 11:07 am June 21, 2016 By Julian Horsey UK inventor Colin Furze has created another awesome project this time in the form of a DIY X-MEN Making Ice Man palm mounted Liquid Nitrogen Freeze Blaster. 11:05 am June 20, 2016 By Julian Horsey Maker and developer Rolf Hut has created an awesome Arduino powered longboard which is equipped with LEDs that react to the speed of the rider and board. The S6 Edge uses its curves to provide a couple of services.The first is called People Edge, which provides a quick way to bring up calls, texts and other messages from five acquaintances of the owner's choosing. The S6 phone's front camera has been upgraded to five megapixels, while the rear one stays at 16MP.
The addition of Samsung Pay, a smart wallet service that allows the handsets to act as a credit or debit card when tapped against a shop's NFC chip reader or used to transmit magnetic stripe data.
The firm also revealed it had developed a new version of its Gear VR virtual reality kit that uses the S6 models as a screen. As PC enthusiasts, we're no strangers to situations arising where performance gets dinged over time.
In short, Samsung's stock 4.4 ROM for the Galaxy S4 employs an exceptionally aggressive dynamic voltage and frequency scaling (DVFS) algorithm.
We ran a bevy of benchmarks and consistently found that the Galaxy S4's CPU complex (and presumably GPU as well) would throttle so aggressively that performance results tanked after just a couple of iterations. With no changes to the hardware design or thermal setup, the clear culprit is Samsung's DVFS algorithm. But the community at XDA-Developers already came up with a hack to disable Samsung's DVFS, essentially unshackling the Snapdragon 600 to perform more aggressively.

This new behavior from Samsung's 4.4 ROM is disappointing for those wanting maximum performance from their SoC, especially given that the new DVFS system actually results in something far less consistent than the two major software versions before it. A positive side effect of such conservative SoC behavior is its effect on power consumption and heat; lower voltages and frequencies generally result in less of both. Special thanks to Zackariah Khazraeinazmpour and Jon Carroll for their help in running benchmarks on their phones to help us characterize performance. There are two versions of GS4: the I9500 with the octa-core Exynos (3G only) and the I9505 with the Snapdragon 600 and LTE.
FIrst off, just because a phone's processor runs at it's maximum capability doesn't mean it's cheating. Hey guys, in the screenshot of RealRacing3, what app are you using to display the clockspeed? Disclaimer: This guide will be using ‘CWM recovery’ as a tool to flash the official firmware on your Galaxy S4 I9500.
First step is to reboot your phone into Recovery mode, by pressing and holding down the Volume Up button, alongside Home and the Power button, until the screen flashes, release the three buttons then. Once, the phone finishes installing the ROM, you need to re-do step 7, but choose Gapps .zip file instead of ROM zip to install the Google apps package. If I turn the screen off by pressing the lock button, the battery will charge at what appears to be a normal charge rate until it reaches 100%. I kept it in a storage room, on airplane mode, only using it to check how much battery it had been once every thirty minutes. The battery life is better but really still not what has been advertised by both Verizon and Motorola. Samsung's head of mobile design was moved from his role in May after criticism of the Galaxy S5's styling, and last week Samsung Electronics announced it would freeze its workers' wages for the first time in six years following a drop in its annual profits.Samsung is still the best-selling smartphone maker.
Most recently, we identified the Radeon R9 290X's bad habit of heating up and shedding clock rate during heavy 3D loads, prompting AMD to introduce a new driver that pushed fan speeds higher to keep up with cooling. Running the exact same tests within the same time window under room temperatures on 4.2 did not exhibit nearly anywhere near the same degree of throttling. We fired up EA's Real Racing 3 and watched the frequency drop from 1890 MHz, down several steps, before settling at 918 MHz. This does not force the SoC to run at full-tilt, as it does under its application-detected Android 4.3 ROM.
Aside from gaming, most phone use is in short, sporadic bursts, allowing the SoC to drop back to idle. Samsung could possibly be accounting for the fact that the first S4s off the line are now a year old with declining battery capacity, and this software tweak will preserve the company's original battery claims. He entered tech media in the late 90s and fondly remembers the days when an overclocked Celeron 300A and Voodoo2 SLI comprised a gaming rig with the ultimate street cred.
If you want to know how to install Android 4.3 Jelly Bean SmartDroid Custom ROM on Galaxy i9500 S4 then read our tutorial below.
This is necessary, to enable you to recover your current ROM install, just in case the new ROM does not perform according to your liking.

Yesterday it ran put of battery after a few hours of Pandora and Google play music (both over wifi). I have looked on these forums and it seems like I am one of very few people experiencing this problem.

The older phone uses the extra space to both run apps of its its own and to add controls to other apps. The Android-powered handsets are also faster to recharge, and should return to 50% battery strength within half an hour of being plugged in. We recently applied Samsung's update to our Galaxy S4 and discovered some interesting performance behaviors that weren't a part of previous builds. At its worst, you'll see CPU complex frequencies of 918 MHz, which is less than half of the Snapdragon 600's 1.9 GHz ceiling. As the CPU complex throttles down, we have evidence to suggest that the GPU scales back as well in defined steps.
It's not clear if this has anything to do with LucidLogix's GameXtend technology; the company wouldn't comment when we asked for feedback. Rather, it raises the thermal limit to what's still believed to be within engineered guidelines. That said, Samsung designs its phones with removable batteries, making it a cinch to replace. Furthermore, these are statistics from applications, not the OS, and I'm willing to bet it's due to lame Java programmers that know nothing about proper memory management. Before going to the tutorial, please make sure you back up all your data because the tutorial wipe your data. In order to perform a backup, select Backup and Restore, then on the next screen, select Backup again. Once complete, go back to CWM recovery menu and Wipe Cache Partition and then Wipe Dalvik Cache.

This is a phone that is advertised as being able to stay in standby for days without dying. Devices aren't cooled actively, so balancing performance, thermals, and battery life becomes a delicate matter of industrial design, materials, and carefully-defined profiles. Nor do we have data to reflect real-world battery life gains garnered from a quicker-to-spin-down version of the S4. It's important to note that installing any sort of modification will void your warranty and lead to risks of bricking your phone. Having a phone that now slows down under heavy load could lead to conspiracy theories now that there's the newer, faster Galaxy S5 heading to stores worldwide. That's all fine in general applications (since Objective C has ARC), but when you develop games in OpenGS, that gets flushed out as you're using C on iOS. Also, please, do mind that this tutorial is only for Installing SmartDroid Android 4.3 Jelly Bean Custom ROM on Galaxy S4 I9500. It's also going to burn through power more quickly, as higher clock rates and added heat work against efficiency. As as the article you referenced reads, "graphically-intensive games naturally crashed the most, while e-commerce apps crashed the least." You can have your outdated, abandoned phone.
