Samsung Pay Framework, as the name implies, is an application bundled on Samsung phones that provides some functionality for Samsung Pay. It's intended to work quietly behind the scenes, but lately, the app has caused major battery drain issues for many users. Read More
OnePlus frequently releases 'Open Beta' updates, where users can try the latest changes before they are ready for widespread use. The builds are usually pretty stable, but since they are intended for testing, issues occasionally crop up. It appears the latest Open Betas have a nasty bug, as OnePlus just pulled them from its website. Read More
Over the past few weeks, many owners of the Pixel 2 and Pixel 2 XL have reported battery drain problems. The February security update appears to be the likely culprit, but since so many Android components are updated outside of system upgrades, it's impossible to know for sure. Regardless of the cause, it has certainly made plenty of Pixel owners frustrated. Read More
If you've flashed Android N's second developer preview and ventured into the battery section of the settings, you may have noticed something odd happening with the History details screen (the one what shows up when you tap the graph) which normally has the expanded battery drain graph with the different components' usage. The latter part is nowhere to be seen in Dev Preview 2.
The graph is still there, but it's stretched across the screen and there's none of the information below it. No cellular signal, no GPS, no Wi-Fi, no device awake, no screen on, and no charging. All of it is poof, gone. Read More
The Nexus 5X and Nexus 6P are packed with a number of cool hardware improvements over previous generations, like a shockingly fast fingerprint reader and a fast-charging USB Type-C connector. During today's presentation, Dave Burke spoke about a brand new piece of hardware dubbed Android Sensor Hub that can significantly extend battery life and allows even more inventive features to these phones. It's a dedicated low-power processor designed to efficiently manage sensor data so the main processor can go to sleep for longer periods of time. Read More
Wireless charging is perhaps one of the best examples of true convenience. The simple act of setting your phone down meant its battery would begin refilling. No need to hunt for the end of a cable, no more time spent clumsily aligning plugs, and no more hassle with loose cords. When the Nexus 4 was announced, its stylish charging orb was supposed to spearhead a movement of wireless bliss. While the orb certainly had its advantages, it was a bit late to launch and carried a premium price. Nevertheless, Qi-compatible chargers began to find a home with Nexus 4 owners. Read More
If we could take a universal count across all platforms asking users what more they want out of their devices, we would probably hear better battery life pretty frequently. As something that many users (myself included) obsess over, we're always looking for ways to get more juice from our devices and find out what processes are keeping us from the illustrious all-day charge. Enter a new app that should somewhat help on the war against bad battery life: My Battery Drain Analyser.
My Battery Drain Analyzer (or BatteryDrain as it shows in the app tray) keeps an eye on your battery, tracking how much it drops (percentage-wise) hour-over-hour. Read More
When it comes to high tech, downsizing is often looked at as a sign of progress. Microprocessors meant whole computers, for the first time, could fit on a desktop. LCD displays made them portable - in the form of laptops. Moore's law proved that chips that once would have been classified as capable of enterprise-level computing now occupy devices that easily fit in your pocket. And advanced lithium-ion batteries meant you could finally take yourself off the AC teat for an appreciable amount of time, and you could charge your gadgets over and over without worrying about the ridiculous cycling fatigue that plagued earlier rechargeable systems.

If you have the ASUS Eee Pad Transformer and keyboard dock, there's a chance that you've noticed the dock's built-in battery draining quicker than it should. This is a problem quite a few users are experiencing, and a member of the Transformer Forums by the name of ASUSFAN001 set out to get an answer to the issue directly from ASUS itself.
As it turns out, ASUS is completely aware of the issue and will discuss it openly with customers. The root of the problem is a specific chipset that is installed in certain units and not exclusive to a specific model number. Read More
Certainly makes sense (get it?), doesn't it. Nearly every EVO owner I know has, at some point or another, complained about the fact that their battery life drops about 5-10% as soon as they unplug it. Well, it turns out that's because of there's an overcharge protection chip inside Li-Ion batteries.
XDA user willy900wonka decided to tear his extended EVO battery apart, and lo and behold:
What I found was that a 8205 chip is used to provide protection and prevent over charging and over-discharging. Here is a quote from a google search.
S-8205A/B Series Applications-Optimized-Battery-Protection Circuits.
All contained voltage detectors are of high precision between 15mV and 100mV depending on the function.
