Overheat Damage from Charging?

Ok so I'm slightly panicking... I forgot to charge my phone 2 nights ago, so I went the next day from like 50% down to 4% maybe (awesome battery life coming from my Gnex!). Plugged it in to charge. Woke up 8 hours later and the phone was pretty warm, but fully charged. Well, I got in the car to go to work and the screen just went black when I tried to play some music and BT, then the phone rebooted. It was still kinda warm so I just turned it off for a half hour on the way to work. Left it sit on my desk all day (busy day) and start using it this evening. So far the phone has rebooted itself twice now on its own. I cleared cache and dalvik thinking it'd help after the first reboot. Is it possible somehow the full charge up and heat maybe broke something? My verizon dev edition is only a few weeks old!

My phone has never gotten more then a gentle warmth to it while charging - are you using the stock power adapter? If it got hot enough to damage it from charging then you should have it replaced.
It also might just need a full reset, but that will erase all data.

All smartphones have PMIC(Power Management Integrated Circuit) on their boards to prevent the battery from being overcharged and having too much current running through such that the battery would feel anything more than mild under the most stressful loads. If a phone(our Moto X) has Qualcomm's Quick Charge 1.0 and is pulling the full 1.1A from a battery at 20%, then the battery is going to feel warm as the current-draw is at its highest from 20% to 80%. Here's a line-graph comparing charge times to illustrate the point where Quick Charge 2.0 was being graphed.

[Q] Sudden battery life change

Hello,
I've experienced a sudden change in battery performance.
What used to take around 50% of battery now takes around 85%.
It happened recently, around the same time I started working at a new workplace. The reception is horrible there, maybe that's the issue. However during the weekends, it is around the same.
I was on 4.4.2 stock when it happened and since then I've flashed it again once. I've also tried a couple of different radios (and enabled LTE) and I've always had franco kernel.
Brightness was always on Auto (which I shall turn off to experiment battery life) and wifi is selected to be off when the phone is off.
I have still a few more experiments to do, but I'm considering using warranty services. What do you guys think? It's clearly not as bad as some of the other battery issues I've seen on this forum, but it's quite the change for me. I bought this phone in July 2013.
Here is an example battery usage graph. Charging finished around 1 AM and left it unplugged over night. In the morning (~7 hours) the percentage was at 75%. (5% / hr) Throughout the day, I have used it for text messaging only and by 6 pm, it's at around 13%.
Thanks for taking the time to read my long post.

You can check what drains battery with BetterBatteryStats. Google it and you'll find.

Thanks for replying.
I have tried that before an OS reset although I couldn't make much out of it. One main thing I noticed was a certain kernel wakelock which, after I googled, was responsible for LTE connectivity. Although this makes sense, I had good battery life even with the LTE chip being used (& auto brightness / wifi always on) prior to this battery incident. By good battery life, I mean 50-60% used by the end of the day

Why won't my phone sleep?

Bought the phone from a friend who never had battery issues. He factory reset it, then gave it to me. I upgraded to 7.1.1 Dev preview last night via OTA.
Location is set to battery saving, no Bluetooth/NFC/etc. turned on. Google Now is Off.
Unplugged at 715am this morning, didnt turn the screen on again until 1045am.

If you are waiting for it to say was asleep I don't think they have that the fact it shows 24 hrs when at 89% shows its not using alot of battery I could be wrong but I have never seen anything stating it has slept

I'm pretty sure, not 100% though that it doesn't state this as it states "awake time" instead
and looking at your screenshots, although its not constantly awake there are breaks in the bars which would indicate it was "asleep"

Sure. Definitely some moments. But the screen was off for 3 hours. Isn't Doze or whatever supposed to kick in? 11% in 3 hours with literally no SOT.

Better question, what could be causing Android OS to keep the phone away for 50% of the time?

For Doze to kick in, your phone needs to be sitting still with the screen off, and not connected to a charger. That means no moving around and nudging the gyro or other motion sensors, no touching the screen or the buttons

You are leaving it and its not in your pocket or anything?

Yes, part of that time it was just on my desk at work.
How soon after all those conditions are met, does doze kick in?

Battery Draining

Hello everyone,
My Discovery elite battery is draining pretty quickly. When it shuts down and I start charging it it starts charging from 0% but when I reset the phone while charging it jumps directly to 24 percent.
I changed my rom, cleared battery stats couple of times, used battery fix and calibrator apps and nothing worked.
Android system and the apps are saying that my battery's health is good, what do you think?
What should I do?

I thought it was just me. I also experience the same problem. It shuts down prematurely or drains fast. After being off for a few minutes and starts it my batt would show it at around 24% again.

Can confirm this is happening to me as well
Are you running a custom ROM? I'm on 4.4.2 AOSP posted by Muratt19

This actually happens in all roms that I used. Even the stock roms.

Have you considered buying a new battery? Thinking of buying a new battery but afraid of wasting 30€ if it's a phone issue

I'm buying a different phone. They practically do not have support in the Philippines anymore. No Service centers as well.

Battery loss over night

Aloah!
I bought the S7 Edge and used it in stock version. Then I noticed that the battery loses over 10% per night. So I decided to install the Superman ROM with root and deactivated some Samsung Features. But the phone still looses over 10% per night.
I have disabled WLAN, BT and GPS. The only activated feature is the always-on-display, but this could not be the problem, because of AMOLED. I know that Samsung bloates their phones with useless things and I only recognize this battery problem (mostly) on Samsung phones. So I think the battery loss must have to do something with the Samsung features.
So my questions are these two:
1. How can I find the battery-using processes?
2. Is there a near-stock-android ROM which is fully debloated? On the S5 the stock ROM had 1,5 GB and then I installed one which has only 400 MB. So there was much Samsung trash removed.

since you are rooted start by installing either Wakelock Detector or BetterBatteryStats app and see the output of those in the morning.
also is it a used or new phone? if its used then the battery might be faulty.
also try 1 night with AOD off and see if that gets rid of the issue.

Its a brand new phone. Ok, I try these two apps.
But what is AOD?

Always On Display :: AOD

Does this really take that much battery? I mean, its mostly black and that doenst consume battery (mostly).

Id bet thats where most of your drain is coming from. Im just going by what I recall, but believe AOD accounts for 1 to 2% per hour.
I like having the AOD at night so I keep it on regardless since Im pretty much able to charge my phone at work or in the car, its not a big deal.

Ok, I deactivated the AOD but still got around 7% loss.
