Battery

I have a known issue.. but with a twist
When.my battery is showing that there is like 90% left. After a while and I reboot, there is only 4% left. That's a.known issue. But here is twist. If I reboot again, its back to 80% orso. And when I do.another reboot there is 75% remaining..
Another reboot shows 74% and so on
I'm sorry if this a known issue.. i don't have much time to search things while I'm working 45h a week.
Anyone knows a.solution for this?
I wiped battery stats. Discharged a few times and the.HTC trick.. non of these work
additional info.
stock battery
HB 1.23
ICS ARHD 6.0.3 before IC and VS
stock kernel
happening for like 2 weeks now

i dont think you can do anything about it. people say that turning off the device instead of restarting helps. i also have battery jumps but not nearly as extreme as yours. maybe ~5-10% jump. if its a drop jump then it will stay there until the real percentage reaches that said level, if its higher then it will drop quickly to the real percentage. from my experience that is, not a big deal

I know that 10-15% drops are normal.
but a drop of 70% is a bit odd.
Its not very serious but its quite anoying, i think its affecting my battery life

Try flashing the battery fix. It helped me out. I had same problem but not so radical.

Use your phone for a while without changing roms or clearing stats, don't charge until your battery is totally dead then don't take of charge until it is totally full, once full turn off and charge till light green, then back on and charge till green then repeat till you feel confident that your battery us full, then go through full discharge and repeat it will settle down but patience us required, remember stay with 1 rom radio and kernel without clearing anything for at least 4 days

Attached is the fix I used to remove the problem with battery percentage changeing after restart.
I do not remember where I found it, but it helped me.

Do i flash this in cwm?

Frequent shutdown and battery drain

Im having problems with my phone battery drain and shutdown. I tried 3 different roms and they all had the same problem. Im assuming it's not the rom. Tried insertcoin sense4, coindroid, and now leedroid sense 3.6. Please help me, i had my phone plugged off for 1hr and it already drained half of my battery. It seems like the phone shuts down because of low battery even though it still has because it dsnt shut down when plugged. When i turn on the phone, it will shut down again unless i turned it on plugged. Please help me... Maybe its the firmware. I rly dnt know. All i know is flash stuffs

Sense ROMS Drain up A LOT of battery :l Perhaps try reflashing a ROM, I would suggest Virtuous Inquisition, and CALIBRATE the battery ( Let it charge overnight ), If your battery still seems to be draining to half a bar per hour after a full charge, try changing your battery~

Okay I'll try that. I'll also check if it has something to do with overclocking

Definitely, overclocking takes up more battery and can damage your processor .

Actually overclocking to 1.7ghz gve me much batter battery using miui but sense roms USUALLY take up a lot of battery but they are pretty much there now eg arhd or coindroid, when you flash a rom drain the battery to <10% and then charger it up fully and you should notice brttery battery.
As for your shutdowns, unless you are overclocking to above 1.8ghz your phone shouldn't shutdown, your battery has most probably just worn out, either order a new extended one or try taking it out for the night and then put it back in, should work then.

Same thing happens to my phone from time to time. In my case it helps if I remove the battery and then press and hold the power button for 15 seconds, then put the battery and cover on and do a full charge without turning the phone on.
You could also check to see if the battery is firmly seated in its bay and if not, wedge something in the gap to keep it firm against the contacts. There is a quite popular thread about it somewhere on this forum.

[Q] Is it battery or ROM or Kernel issue ?

Hi,
My phone is almost not charging full or it doesn't show as such.
This is detailed breakup of my issue :
I put phone at charging exactly at 2pm at 2%
3pm it was at 36%
4pm it was 54%
5pm it was at 64%
6pm it was at 73%
7pm it was at 82%
7:30pm it was at 84%
after this I removed phone from charging and rebooted it. Surprisingly it showed 100%.
Battery doesn't last more than 12hrs no matter what I do. I am using Greenify too.
BT, GPS, Auto-Sync, 3G, etc all are off. WiFi On 24hrs.
Screen-off battery drain is also around 8-9% per hour.
Can I do/try something on software side before I order a new battery ?
Right now I am on Carbon ROM (20131008) with stock kernel, 1512, Ondemand, SIO, No OC. Its same on every ROM I tried except seemingly on ARHD 7.3 (used it less than 24hrs. Its rock solid and smooth.)
I would greatly appreciate any help/advice !

I also has this issue still looking for the solution

the battery misreading while charging is a common htc's fault after rooting and there is no solution yet
i have the same thing while charging my device
but the difference is i don't have that fast drain
how old is your battery?
did you try a different battery?
make sure it fits correctly to the pins

Battery is just 1yr old. Yup I checked the pins. They are correctly fit.

this is a rom issue i think as this has also happened to many people and and this happens after many days on a single rom (and u make the rom unstable)
the solution is simple just backup ur data and full wipe and flash rom again and u will be good to do for next many days (if u keep the rom stable)

I flash ROM almost every alternative day and I always do Full-Wipe

Battery Kernel issue
I am new to xda. I actually flashed a new rom after that phone doesn't charge after switching off. Could it be a kernel issue or the rom's issue. I have a Canvas HD. And sorry if this is not the place to ask the question. I couldn't find any other thread related to this. Please help.

Similar issue here. My charging often stops at about 80%, but after a reboot the battery's full charged.
My battery also gets drained very fast, but it's about 2,5 years old so that's probably the problem.
With the CPU clock speed @1,5GHz and the GPU @266MHz i get about 15h +/-2h of battery life.
I keep battery saving ON most of the time. Bluetooth, GPS, 3G etc all OFF. WiFi ON for about 1-2h per day (if i would keep it on longer, my phone would be dead in 4-5h).
I'm using ViperS 5.2.1 right now (full wiped before install). I got the same experience on ARHD and previous ViperS versions.
Tested the charger - it's fine.
I was wondering if anybody else got an old battery like mine and how long does it last on full charge

Hi guys,
I have a HTC Sensation XE that i bought three days ago (second hand) and i have the same problem with the battery % not reading correctly.
Now this is what i observed:
- the charging is very slow - from 20% to 40% in 2-3 hours
- after 2-3 hours of charging if i reboot the phone the charging LED turns green and the battery reading says 100%.
(i tested to see if actually it got charged to 100% and it did, i turned everything on, watched a HD movie, played some games and after 5-6 hours of playing with it i still had 50%)
- tested the battery to see how fast it drains from 10% to shut down and it went on at full brightness and everything on for about an hour and something so this means there might not be any problems with the battery
- so the reading is wrong because the battery is charged after a few hours.
- i did a test to see if the same thing happens when the phone is off and i left it to charge for 2-3 hours and when i got back the charging LED was still orange. When i started the phone the LED went off and back on as green. The battery was 100% charged.
- If the same behavior happens in off mode it means it's not a ROM problem (by the way from what i know the phone is stock, the guy never did the rooting.....that's what he told me - can't know for sure).
- from my electronics background it seems the phone updates the battery information sometime at boottime. When charging, the software keeps the charging LED on because it's supposed to charge due to incorrect data but the hardware charging controller drops the charge current because the the battery is full. So this can be an incorrect sensor reading by the software or an incorrect feedback given by the hardware controller.
So what do you think, what can cause this.
Should i try rooting the device?
And i tried factory reset from android and factory reset from bootloader and the problem is still there.

Ok so i did the following:
- unlock the bootloader
- flashed CWM
- installed superuser
- wipe battery stats
- wipe device
- calibrate battery with an application from market
The problem is still there.
I figured that when in bootloader first thing you can read is the S-ON/S-OFF. Before doing the unlock it was "LOCKED" and after "UNLOCKED".
I did a relock and the status changed to "RELOCKED" so this means the guy that had the phone before me didn't root which again means the theory that says this problem occurs when the user tries to root the device is not true because it seems the behavior is observed on an unrooted device.
I will dig deeper maybe i find more ideas on what i can do.
I'm running out of software options so this is pointing at something hardware.
I'll get back with updates when i find something else.

probably it is htc's bug
the same happened to me after rooting the device

For now I will try to make some full cycles of the battery and see if anything changes. I usually use the phone at work and by the time I get home it's almost empty. Plug to charger and till morning it's full with a green light. I will have to monitor the charging times and get back with results.

Well i did some full charging cycles and nothing changed, still the same long charge time(read by the phone) and with restart it bounces to 100%.
I had the original Android 4.0.3 with Htc Sense 3.6 at the time. Got 4EXT recovery and an 4.0.4 rom with Htc Sense 4.1. Did a full wipe and battery stats , installed the new 4.0.4 rom but the problem persists.
At this point i think the battery is the problem so the next thing to do is to change it. I will get back after i change it, hopefully sometime in november.

After a long time I managed to change the battery and after a few tests it seems the problem is still there. The time on battery improved as I expected but everything else is the same which means it's something hardware defective in the phone. Also did some tests with android 5.1 and the same results. Meantime I sold the phone and got a Samsung Galaxy S3 Neo. Hope this research gives some answers to someone at some point. Cheers.

[Q] Sensation battery and overheat problem

When i was using stock HTC sense in my sensation i faced the following problems;
1)Very fast battery drain if i browse the internet or use any applications(battery falls by 1% every 1-2mins)
2)when battery is 100% after just playing for 5-7mins(plants versus zombies 2) the battery falls by 25% to 75% thats a huge drop.
3)And when playing games just within 5-7mins the phone overheats abnormally
4)the battery part is not very hot but the bottom part below the battery slot is very hot(mostly when playing games)
I rooted my phone and im using vipers 3.1.2 rom but the problem still presists
the battery readings are not accurate most of the times for example sometimes when i have use the phone for a long time the battery still remains the same but after a while the battery drops significantly every second.
My question is is this a battery problem or is the motherboard/cpu of the phone causing these problems.
there is no expert in my country where i can get technicians to check the problems so ur advice is highly appreciated.

How old your battery is? Are you using any third party battery like Anker or Mugen?
Battery stats miscalliberation is a common thing and almost all of us face this issue after flashing a custom ROM. I guess you should give some complete charge cycles and it will get back to normal readings.

Mine after 2 years was in such bad shape that the phone kept dying ~5 mins after opening FB, and that is with low brightness, underclocked. Also the battery itself became bigger, instead of being flat it became... how do I put this... chubby I figured it's because of overheating.
Anyway, switched to Anker, it's much much better now.

I am facing overheating problem
I am facing overheating problem on my htc sensation xe. I am running vipers 5 rom with 1.5 GHz (standard frequency for htc sensation xe).
What I have observed is, whenever phone overheats it eats lot of battery. My battery is only about 2-3 months old. Any work around for over heating problem?

[Q] help? Batterry precentage

Hi Guys, i'm noob, i wana ask about my htc sensation, after 2 year i'm using it, today i found
when battery charging (htc Senstaion) dismiss displaying percentage of battery after i restarting while charging.
****battery charging ------> Battery percentage displaying 60% then i restarting the phone while this situation
and then when phone finish restarting and ready to use battery precentage displaying 100%(full)
is it normal?

edit: the point is the battery is increasing its percentage slower when it passes 60%-70%
but it charges the same
so if you reboot the device then it jumps at 90% or full charge

Is it known what causes this?
Someone above said "it is a htc's common issue after rooting". Is there any source on that? For all I know, percentage of charge of battery is determined by a combination of output voltage and amps, preferably referenced by a table taking battery age into account (correct me if I'm wrong though).
Rooting the device should not be an issue, unless HTC did something in their rom to detect this and let the battery percentage be wrong. Then again, most of us aren't on the stock rom. To be on another rom, the bootloader needs to be unlocked. Did HTC do something that unlocking the bootloader makes voltage/discharge readings unreliable? I doubt that...
I'm interested in this because I unlocked and flashed a Sensation XE for a friend of mine (SultanXDA's KitKat rom), but the battery discharges very, very fast, without an obvious cause. So I wonder whether it could be the battery is not fully charged and/or the phone decides it's empty to early.

"it is a htc's common issue after rooting"<- i said that
it was a source but i can't find it now
also i don't know if htc did something with unlocking the bootloader by purpose
if you flashed the rom recently don't judge the battery too early
give it 4-5 cyrcle charges until it settles down then see how it goes

I have exactly this problem.
It sounds like the same ROM, Saltan kit kat. I am using the latest kernal 3.4, having tried two kernals I get the same results. For example I charged the phone to full, and after 2 hours of use I'm down to 55%, WiFi on and browsing, gmail synced but not much else, screen brightness turned down etc.
I only flashed a couple days ago, will it improve massively over the next few days?
The phone was giving a days charge easily before flashing.
I am also noticing a message saying 'unfortunately process com.android.phone has stopped working' (or similar). When this happens and I click OK I notice the signal disappears for a few seconds before coming back. Could this be the cause of the problem?
Could it be he ROM?
I'm new to all this but managed to unlock, root, flash recovery, and flash the ROM thanks to the brilliant guides on XDA. Any help with the above would be appreciated.

This really sounds like your battery, especially if it's not the original or equivalent. But, it could also be an app on the background, keeping your phone from "deep sleep". Bad cell coverage (very low signal) also drains your battery relatively quickly when you're on 3G. A good WiFi connection consumes less power than 3G with bad signal. Another possibility could be (but unlikely) is that your phone is intended for another region and thus having trouble communicating with the GSM network.
- Check your battery.
- Check what your battery is used for.
- Check your battery time with network set to GSM only.

Still you keep saying "after rooting" which is significantly different from unlocking the bootloader and flashing. Furthermore, to me it seems far more people report "better battery life" with their new roms.
About initially flashing the rom: i thought format of system, data and cache (including dalvik cache) ought to be enough. It has had somewhere between the 10 and 20 charge cycles by now. Battery life improved a little, but it's still far from acceptable. The battery percentage between reboots should only differ marginally between reboots (might need a few minutes of usage to become accurate). Also notable: over 20% difference in percentage reading between rom and recovery.
I wouldn't mind investigating this. So I wonder if anyone with "proper" battery life could provide me a "dumpsys" for the battery service and would perhaps have the time to take a look at /proc with me.

The battery percentage between reboots should only differ marginally between reboots (might need a few minutes of usage to become accurate). Also notable: over 20% difference in percentage reading between rom and recovery.
I wouldn't mind investigating this. So I wonder if anyone with "proper" battery life could provide me a "dumpsys" for the battery service and would perhaps have the time to take a look at /proc with me.

i unlocked the bootloader and root the device at the same period and i stayed for months with the stock rom
i don't know which one is responsible for percentage misreadings
also don't get confused
i am talking only for percentage misreadings and not for better battery life
and only when you charge the device.not unplugged
of course i had(and i still have) very good battery life with whatever rom i have flashed
by the way i have noticed the percentage difference between recovery and rom but i don't remember if it was 20%

Alright, thanks for clearing that up. I really want to solve this issue, so I'm quite keen on getting the facts straight.
Back to my issue then (yeah I'm effectively hijacking this thread): is it possible the percentage misreading is causing the battery not to fully charge and/or discharge? Or should I direct my search to another cause?
This is what I found (or did not find) so far:
- Stand-by time seems great, the drain occurs when the screen is on.
- There is nothing in the normal battery usage (usage goes to screen)
- I was unable to detect an obvious culprit with better battery stats.
- I did notice that when I do a dumpsys, service battery shows voltage in V, while my Sony shows it in mV.
- I tried offline charging for about an hour today (light still orange), after boot the battery indicator showed 100%. It dropped to 86% in 7 to 8 minutes.

probably never truly reached the full charge(100%) when charged it in that one hour
by the way how old is your battery?
did you try with a new one?

since you are completely stock then the only thing i can tell you is to check your battery if it fits correctly
also how old is it?

please see attached screenshots
what do u think , is this battery or some hardware etc fault??
