Does anyone else's battery history reset after a reboot? The percentage amount is fine but the up time and screen on time starts from scratch again. On 4.2 but this also happened on stock rooted 4.1.2.

It's supposed to be that way. It would be rather pointless if they didn't reset.

It doesn't do this on my phone though? You can see the small gap where the system rebooted but it continues as its on the same charge.
Slightly annoying as sometimes a reboot is required or you need to boot to recovery and the history starts again still you lose track of what battery life you're really getting.

I haven't tested it but if thats the case , its ridiculous.. Battery stats should always start from unplugging time, otherwise what is the meaning of it? That must be a bug..

Thanks, I haven't modded or changed anything apart from unlocking and rooting. Happened to notice it and thought I would ask about it, since my phone behaves differently. Everything else is fine though so its not a big problem, but would rather it worked correctly. Wondering if I should full wipe from recovery and reinstall apps one by one to see if it helps.

Uptime is a measure of a system's availability without interruption. Time on AC power is also counted as uptime, and a reboot resets the clock on that, as it should. Uptime is not synonymous with time on battery- they are two separate concepts. A reboot, by its very nature, interrupts that availability of the system. Were the uptime not reset at this point, that particular metric would be utterly meaningless since it would be grossly inaccurate.

Update:
Well the battery history/time is now sticking after a reboot, i.e. showing 19hrs on the current charge (after both power down/up and reboot. Surely that's what its supposed to do? That's the way its worked on all android phones I've seen.

After double-checking, it looks like we're talking about two different things. What you were referring to as uptime is the time overlay on the graph, correct? If that's the case, then that is not uptime and you are correct in that it should only reset after charging. Uptime is displayed in Settings >

First of all, I know what most people will say: wipe battery stats and condition the battery, but I'm too lazy.
So recently I've been noticing that sometimes my battery charge percentage goes up rather than down. For example, tonight I put my phone in my pocket at 18% battery left. I watched some tv and checked it again ~1.5 hours later to find that it was now at 32%. I've seen this happen on occasion before, but never such a significant jump.
Anybody have any clue as to why it would do this? Other than the fact that my battery stats are needing to be wiped. idk just seems weird to me

Sometimes that happens after a random reboot, where when it comes back up, it has "dropped battery." Then it realizes it isn't actually that low, so the battery meter will climb till it actually equals the battery. Then it'll start dropping again.

That was happening to me on Clean GB, I reboot my phone every 4 days or so and my percentage would drop significantly after booting back up, then start increasing. I've never wiped my battery stats. I'm using another stock-like ROM so I'll see if it happens again.

When you reboot do it while plugged into a charger and that won't happen. It is a glitch in CWM and battery stats.

"Conditioning your battery" after wiping battery stats takes nothing more than regular usage of your phone. All the people that say you have to do all that stuff after calibration are just recommending it because it causes your phone to adjust faster.
Just charge it all the way and use battery calibration to wipe stats. Your battery life will take a few days of use to improve to good levels, but it works and you don't have to do anything other than what you normally do with your phone.
Hello
My friend have a Nexus S (9020A) the problem is when the battery dies it's impossible to charge the phone, it won't turn on! I have tried with a lot of batteries now and it kills all of them! it works like normal when you don't let the battery die completely but it should not do this anyway, what is wrong?
I think I know what your talking about.
The phone consumes more power than it receives when its using data. Do if your at 5% and charging, but also using the internet. You will last for mere minutes.
Best thing to do is to simply let it charge and not touch it when its doing so. You can still hotspot,text talk. But streaming music, data apps (like tapatalk or skype) and web browser WILL KILL YOUR BATTERY WHILE YOU CHARGE.
But if your saying it won't charge. Sorry. No idea

The phone should shut down automatically when the voltage reaches a certain threshold. Is the phone not doing this? These batteries are not meant to drop below a certain voltage and doing so could damage them.

This is so insanely inaccurate. Using the hotspot is one of the most battery intensive operations the phone can carry out. Streaming music, Skype, and browsing don't even hold a candle to it. The only thing that comes close would be navigation (and that can be even worse sometimes), followed by talking on the phone by a pretty decent, but not massive margin. It also depends on the charger. Where do you get your information?
Sent from my PG41200 using Tapatalk
if the phone is doing the same with all type of ROMS, then it may be hardware related issue.
I have been running various Roms since the start but never faced this issue. A lot of times battery has drained fully. With some of the new roms that are there my phone lasts more than a day with Data on Roaming full time.
I know most phone batteries will not be chargeable if you deplete them completely. Usually this happens by throwin it in the drawer and not using it for a long time but ive never heard of it happening just by using the phone. Id say its definitely a hardware issue

Yes, I have to agree. This has also happened to me. I have actually had this happened when I turned my phone off one day. Before turning it off it had 60% battery, after a minute I turned it on and it said 20% battery. Also, has it happened to you that you charge it leave a couple of hours and when you unplug it rapidly falls to 70% or less? LOL! But it is nothing a full charge and batterystats.bin wipe wont fix.

Wiping battery starts has nothing to do with reported battery percentage. Similar results can be obtained by setting your phone face up on the coffee table, watching any random show on tv, and doing Zumba for 30 minutes. In other words... none.
Battery stats, which is only a list of the apps that have put a demand on the battery, is already cleared each and every time the os is rebooted

This is what I have read on the XDA forums and it has worked for me.
Completely charge your phone to 100% (Full battery charge) without unplugging. Once it is charged, without unplugging it, reboot to recovery and wipe battery stats in the ADVANCED section. As soon as your wipe it, very quickly unplug the phone. (as fast as possible). Once you do this, reboot your phone and completely drain it to until it turns off and you cannot turn it back on unless is plugged. Once it is drained charge it completely full withot unpluggin it or turning it on.(Best time to do this is at night, since you are probably not going to use it while you sleep). After that just use it daily. You have to give it a couple of days so the battery syncs up. Hope I helped out!

No offense, but what you have read is incorrect and is rooted in a misunderstanding about how the os and li-ion batteries work.
1. Wiping battery stats does nothing pertaining to charge indication. The file cleared is an already blank file that lists nothing more than a list of the apps that have consumed power. This file is cleared by the is on every reboot already.
2. Completely draining the battery shortens its serviceable life.
Any "results" that are seen by doing the above are merely attributable to the placebo effect.

Noticed this on both 4.2.2 and 4.3. I've tried .48 radio and .83, stock and PA, stock kernel and Franco, heard it's common on CM also.

your android os looks normal. seeing that you didnt use the phone much, your screen on percent is lowered. since your screen on percentage is lower, all others will appear higher than you would think they should be. but if your screen was using 50-65% of the battery as it would for normal use, then your other percentages would be lower. anyways, your android os is normal. what i would look for is an app in the background behaving badly, or disable a notification or two if you have many. if you have root, i would install greenify and then greenify a bunch of apps.
my android os usually hangs between 4-8%, but my screen is usually around 60%(with heavy use).

i never look at wakelocks, that is how our device is supposed to work. granted, occasionally an app will create a wakelock that gets stuck, but thats just bad coding on the app by that developer. watching wakelocks will waste more of your time than its worth. take control of your apps instead, dont let them run rampart.
Neither BBS or Wakelock Detector is helpful in diagnosing Android OS battery usage. Most of the time it shows as PowerManagerService.Wakelock in Kernel Wakelocks, and pages from google state that is it a sum of Partial Wakelocks adding to PowerManagerService.Wakelock. But there was one time I had a 15 hour wakelock from PowerManagerService.Wakelock and looking in Partial there wasn't anything really significant, most entries being 20mins or something at the top of the list, 10 minutes on the next, and so on.
Whatever it is, it's particularly bad on 4.3 both on my Nexus 4 and Nexus 7.
So I listened to some music for roughly 20 minutes in the car. Set my phone down to watch TV. Came back 45 minutes later and it dropped ~25%. This is WITH 3.5 hours SOT. android somehow still takes top spot. Help?

Everything was fine after the 4.4.2 update until a couple of days ago. I noticed a heavy battery drain during the night - approx. 20%. The conclusion I made: Android OS is back. The WiFi was on, but the router was off, so I though it might have something to do with it trying to establish a connection.
This past night I turned the WiFi off and left the 3G on. 10+ hours of wakelock from Android OS and 30% drain. So, what am I missing here?
The worst part is that those f"%^* from Android developers team has disabled any reporting from the running processes in the latest version.

You can use the stock google app to find what google app is running during the wakelocks. Just go into Settings -> Apps -> Running tab and see what google process are running. Then download and use "Disable Service" from the playstore to find and disable the suspect google apps.
My phone would stay wakelocked after a call or gmail check all because of gcm_google service. I disable it under Playstore services using Disable Service and my google wakelocks went away. Worth a try.
same problem here
misuse of wake locks can easily lead to energy waste
"Android os" usually is the kernel while "Android system" is, well the system. Try changing kernel, it fixed the issues for me.

That happened to me once or twice. These spikes are only visible on the battery graph in settings app. I use an alternative battery monitor app from Google play and it does not show any spikes. Also battery life seems pretty in line with what other people report. I simply ignore them since they do not seem to affect battery life.
Could it be caused by the wireless charging functionality being triggered by other electronic devices in house?

Hey everyone,
My Nexus 7 (2013) is having the same problem with battery graph. There are about 2-3 spikes to 100% in every discharge cycle.
I noticed this problem has been reported in different cycles, but no one seems to be able to give a definite answer of what the source of this problem is.
BTW, after a reset to factory settings, the problem still persists.
ANY idea why this is happening???

I'm not sure what's happening. My Nexus 7 remains idle most of the time, yet I get pretty bad battery drain and then when I check the battery history I see this. This happens during every battery drain.
Any ideas guys?

You just keep referring to that forum without actually answering my question, even on that forum
