Battery charge from 80% to 100%=(

Hi, sry for my english=(
When i charge my battery its normally charge to 80% and then becomes 100%.
Try calibrate battery but this doesnt help. Also try another roms and kernels.
Is it a battery issue?

U can buy new battery from DEALEXTREME.com

so its the only way?

Try this.
Charge battery to full. Leave plugged in, Turn off fastboot in power settings and shut phone off. Light will turn orange again and let it charge til green. Boot into recovery and wipe battery stats. After this let the battery drain as low as 10% before recharging to full without unplugging. Do this a few times over a few days. If you don't get more accurate percentages after this then the battery could be messed up.

thx i will try.

i have the exact same issue. i have done battery stat wipe..flashed multiple roms over and over with full wipe and all that. battery charges up to 80% then the LED turns green..and stays that way till it reaches 100%. it jumps from 80% to 100% in just a few minutes.

battery jump
I wouldn't worry Lendlord mine does the same (see attached pic) you can see the green line jumps up from 80 to 100 but doesn't jump down from 100 to 80 under use. The picture is taken from Battery monitor widget, it's a great app which shows mv, ma, % and temp and even keeps a text log of what ma drain there has been allowing you to monitor battery drain while you're using your phone or while it is sleeping.
Here's a great guide aswell of how to ensure best battery life by memnoc:

so thats mean that some battaries have the same issue=( And there is no solution for it...
HTC failed again...
first GPS and now the battery. Bad, very bad!
And one more request.
Can someone post your current widget log?

I have the same thing happen to mine, i think its because you've let your DHD die due to low battery levels and that damages the battery which i think causes this problem

..letting the phone shut off because of a completely discharged battery is NOT good for the lifetime of Li-ION batteries.
The battery could be hurt and the amount of mAh the battery is able to store might be lower after.
Also trying to 'pump' the battery to fully charge by connecting / disconnecting while the phone is down is not a good advice because li-ion batteries also don't like overcharging.
To be sure that the battery is fully charged due to its ability it is sufficient to let the phone be conectet to charger or usb overnight.
Android uses the voltage of the battery to estimate (!) the % charge value.
Android supposes the battery is fully charged when it enters the voltage of about 4.2 Volt which is the charging cut-off voltage for li-ion cells.
Now when charging again the conceded voltage is reached more quickly than estimated by android, so the system is 'surprised' of this rapid charge and changes the % value to 100% because the conceded voltage is reached more quicklyy as supposed.
(Try to fill a 0.5ltr beer bottle into a 0.33 glass)
This is the normal of aging for li-ion batteries.
Consider for yourself if it's acceptable for you or if you should by a new battery.
by the way... be careful with cheap china batteries for 10$.
Offers with exaggerated values (up to 1600mAh) will mostly keep their promises
only for the first two or three charges only and will than fall back to 800 mAh or even less !

Yeah...
My battery started to do the same thing for a week or two. It will charge to 86% then it jumps to 100%, saying it's charged.

This is normal afaik, nothing to worry about.

actually，it's the problem of your rom , in the framwork.apk . unzip it you will get a lot of battery icon form 1%to 100% in the res file ，if it made mistake，that 'your problem. you can go to uot kitchen to coustom it again.

Nope!
I've solved my problem. I've bought a new (original) htc battery, and the new one works great. I haven't reflashed the rom, or made any new modification. Just added the new battery.
So, yes, it's a faulty battery.

Htc Desire Shuts down at 40-50% battery

Hey guys,
Assuming you have read the title there is something weird about my phone.
It shuts down at 40-50% battery (before it shutsdown it says empty battery briefly and then the htc flash screen appears and shutsdown).
The weird thing is the following:
It shuts down at let's say 40% battery, but when it re boots the battery is litterly empty (even when i boot in recovery it says --%, and when i plug the charger it starts at 0% again).
I have tried:
Battery Calibrator
Empty full fill up with wall charger and also tried usb charger.
Screaming @ phone
wiping battery data in recovery (4ext recovery)
The thing i am most confused about is that it goes out at 40% and when i turn it on again it's 0%. This never happened as it happened for the first time 2 weeks ago, confused. I tried different roms and it still happens (even ICS roms).
I wouldn't really mind if my phone would shut down at say 20% when it says actually it's @ 20. But as i said before: It says it's 40 (batterij indicator htc sense half full) and then shutsdown realizing after reboot it's completely empty.
Any help is much appreciated!
Mendel

Shutting down on let's say 15-20% is quite normal, but I never heard of one shutting down at 40%
Are you using the stock battery, that came with your device?

Any chance to try another battery? Seems really strange cause in most cases if you wipe battery stats you get your phone shutdown at 20%, not 50%.

Its most likely a bad battery that needs to be replaced specially if tue same thing happens when using a different rom.
via xda app

Yeah i know it seems so weird that's why i started this thread.
Before i buy a new battery:
What could be the cause that the phone goes out at 40% (or 30) and when it reboots it's empty.
Seems like the phone or the battery aren't in "sync" until it reboots to show it's empty.
Any tips or suggestions?
Thanks!

I'd like to think of it similar to laptop batteries that have gone bad... you plug your laptop to it's power supply, it says fully charged but as soon as you pull it out from it's power supply it drops to 50% in minutes and then goes off. The battery cannot hold the charge anymore.

It can only mean that the battery's life is at an end. The only thing you can do is to change it. I suggest that you stick to original HTC battery as the "ChinaMade" ones will die a lot faster and you'll have to change it sooner than this one.
Regards.

Hey guys!
I know this thread is started since several months but I actually have the same problem : I have a HTC Desire and its shuts down at about 50% and when I reboot it, it says the battery is empty.
I tried several times to recalibrate the battery (and to do all the things MendelMusic said in his post actually) but nothing changed.
MendelMusic, did you finally manage to solve your problem?
Anybody have a solution or any ideas?
Thanks!

Battery drain?
It's called battery drain. I have it too, but only at 10/20%?
If someone knows a fix, please send it to me

AW: Htc Desire Shuts down at 40-50% battery
Probably your batteries are just weak now. I'd recommend you all to invest 5 bucks in a new battery. Actually that helped at my old desire. Greetings

Thanks for your answers!
I tried the link of madreef and it didn't change. I will try again, maybe I did it wrong (hope it will work this time...)
@dschibril : I don't think my battery is weak because the problem occured as soon as I changed the ROM (CM10). The battery was perfectly ok before that.

Hello, I have the same problem with you. Did you manage to fix it and how? Have you tried a brand new battery so far?

It has to do with the Desire's poor battery age management system. Li-Ion batteries age, meaning that, as time passes, they're gonna be able to hold less and less milliamps. After almost two years, my Desire's battery can only hold 82% of the original ~1400 mA charge.
The only way around this is to use the Nexus One Battery Calibrator (Nexus One and our Desire share the same hardware underneath the hood). You'll need a compatible kernel and some patience. Instructions in this post.
My 2 cents: if your battery is only able to hold less than say 75%-80% of its original charge, then you should replace it. Li-Ion batteries age in such a way that they suddenly go dead, so it's not worth taking the risk.

Later Edit - If your Desire shuts down at say 40% - 50%, that means that your battery is 40% or 50% gone, so it's time for a replacement. I'd still try the battery calibration method i wrote about in the above post, just to determine if it's a freak software error or the battery's fault.
P.S. - Wiping battery stats does nothing to solve most issues (for the Desire, at least).

My phone turns off sometimes at 50%, sometimes at 80% of battery.
I have new battery now (original one) and it is the same. Phone turns off, only when it is connected to charger it does not.

Hiii
My hTC Desire 728 shut down when then battery showing 50% to 60% in charge. What is the remedies?

[Q] Galaxy Gio New Battery charge so fast and drain also

Have a good day .. Tech at XDA
My Samsung Galaxy Gio Battary Charge quickly and drain in a similar style. I buy new battery but situation remain same. Battery Stat from 8% to 15% to 30%...55% and some how stop on 80% in just 15 to 20 minutes.
Please help.. Is it battery problem or charger (I buy new charger also) or some kind of IC circuit problem.
Thanks in ADVANCE

Drain your battery to 0 percent then do a complete charge from 0% to 100%
Worked for me.

I have the same problem.I tried two different batterys and from both i get the same result.I think it's a problem with the sensors,when it reach 100% stops charging but in reality isn't charged at all.

Did you recalibrate the battery?
Here is a link to an app in the google play store
http://goo.gl/xRHjp7

I discharged it yesterday and then it charged completly in 15 minutes.I see in the app's screenshot that at 66% he has 3882 mv.On my phone at 100% it shows 4mv.

Solution for battery drain on Tab S 8.4

Hi everyone.
Just to write a solution for the commonly problem on the battery of this tablet; I had the problem that battery ran out almost on 1 or 2 hours! of use after it turned off I turned on again and the gauge showed for example 30% or some cases 40% of battery I was crazy about that and had to do some research; tried to bring the tablet to warranty but they did not could help me (I don't know why) after that I read there were more users having this problem; some of them suggested to bring the tablet to a repair center or open the tablet and do some technical reparation; the solution is pretty simple that it seems to me; my solution was to open the tablet with a spudger (I don't have one so I made one by sanding a piece of plastic) after that just unplugged the battery conector and reconnected it again; rebooted if recovery mode and erased batterystats.bin, turned off and charged until 100%.
At this point I have been using the tablet by 3 days and the gauge seems to show a more precise battery percentage.

Anybody that is having battery problem, and have checked that a app is not causing the battery drain, should try the battery calibration method below, before opening their tab
Try apps like watchdog or an wakelock checker app, also any apps like alarms and weather check apps or any apps that sync the tab can keep the tab from going to sleep.
On my tab s 10.5 i only charge to 70% and never unless i am doing a calibrate drop below 20%, I use my tab for video, ebook and internet.
I use an app like Gsam to sound an alarm at 20% and 70% when charging, and i dont charge to 100% as it can cause cumulative damage to the battery, check the link below for more info on how to care for lithium based battery`s

Below are a few screenshots from my tab s 10.5 , It has been running continuously for 142d without restart and i have a battery life of 3d21h according to Gsam app.

You can calibrate the battery like this before you decide to buy a new one
Fully charge the battery with the phone on and when the phone is fully charged, unplug the charger and turn it off.
When your phone is off, plug it into the charger and let it charge to 100% again. The green LED light will indicate when this is don
Next unplug the charger, turn on your phone and set the option to ensure that your screen doesn’t turn off, if you have this option. Then reconnect to the charger and wait for it to charge again to 100%.
Once charged to 100%, unplug the charger again and do not charge until the smartphone turns itself off after reaching a 0% battery level. Once off, fully charge it again and it should work properly. The screen setting can put back to normal again (meaning turn off after a certain amount of time).
phones with oled displays should not show static images for a long time as it can cause burn-in

I might have to give this a try. Like my battery has no problems with its connectors or anything since I have never had that problem. Recently, every time I charge my device, when it charges up to 97%, it immediately jumps to 100%. Rebooting still shows 100%. So when I turn off the device and charge it while it's off, it shows its at 98%. So I know it's an calibration problem. This only happens when charging up to 97%. So I might need to recalibrate again.
-DUHA

You should not discharge to 0% too often, as it can causes curative damage and the battery could actually fail, you would not want that to happen if you are out of warranty, I rarely discharge below 20%, a couple of % inaccuracy is not a problem really.

I hardly ever discharge to 0%, I usually charge it when it tells me my battery is low (20-15%). Well, I bought this tablet in July so I have reached probably 300+ charge cycles. I read some threads regarding battery skiping and it happens when either it's uncalibrated, or battery is slowly going bad, and something else I forget. But thanks for the tips on the battery stuff! I never knew charing and discharging fully could do such a thing!

I bought my device from Kuwait so it's firmware belong to united Arab of imarats.
At the beginning , I faced some issues with my device such as. After about 3 weeks I found the the battery stay only for 10 minutes even if it charged to 100%
I had to put my device in charge all the time so I can use it.
I send it to repair center and told them that I need to replace my battery.
After one day they call me and told me that it just asoftware problem and we solve it.
I got it from them use it for just 3 days and found anew problem that the home,back and multitask buttons dosen't work very well . That I need to but it on it's back or use the desktop cover to make it work.
In that point I tried another country firmware with kitkat 4.4.2 and that dosent solve anything
And when I found that the lolipop came to galaxy tab s with France and Canada and sanghfore , I installed it
I found that when I connect the wall charger , the device immediately turn off and give me the sign of battery with out any process in charging and dosent want to turn on.
And when the device work , it give me ablack screen when I shake it between my hand or but it on it's back (such like ablack screen flashing)
I don't know what to do.

Problems with battery

Hi, I picked up my phone from repair shop a week ago and since then when my battery goes below 55% i get message that battery is 0% and phone is shutting down, and then I put it on charger and sometimes it starts recharging from 1% but sometimes from 55% and if i charge it to 60% it works normally, but when i charge it to 100% it turns off on 55%, can someone help me please is it problem in software or maybe it is problem in battery?

I replaced the battery and it's been working well for a few months now.

Battery drop from 50 % to 0 %
I had the same issue.
After force shut down (power + vol-up for 10 sec), the battery went back to normal.

That was a short lifesaver, battery is "fubar".

Guys , maybe there's something wrong with the battery charging in Amami . I have two Z1C, one of which normally charge up to 100 %. But the other charges the battery to 100% only in Stock 4.4.4 ... In all versions of Lollipop (stock or not) battery charges to 82% ... Calibration of the battery does not help. I replaced the battery - no change. I tried another powerful charger by Samsung - without effect. Anybody have an idea what's going on ?
