Battery dying for no reason

Hi, I am using Cyanogen's v4.1.999 and noticing a weird behavior on my G1. I charge my phone and it says its charged. Then after some hours if I try to do some stuff like browsing or downloading/installing software it just turns off from nowhere, and when I bring it on again the battery is under 15% and I got the dialog to connect my charger. The problem is that its like my battery meter is nuts, or my battery, or my rom.
Has anyone seen anything like it?

Not the ROM definitely a hardware issue. Also try to put questions like this in the Q&A, some people get pretty touchy about questions in the Dev forum.

For sure 100% it's a hardware issue

Anyway to test if its a battery or phone problem without getting a new battery?

well you can just call htc and they will replace the battery free as long as you send the old one back. theres a thread in accessories about it

I had the same problem with my G1 i will charge my phone all night and it will only show battery is charge 5% so what i did is went to T-Mobile got a new batt that was $39.99 and a wall charger that was $19.99 and took it home and charge it for 48hrs and i sill got the same 5% batt charge so i call HTC and told them my problem with my G1 and they told me it was a hardware issue they ask to send them my G1 and they will give me a replace for free
i got it with in 7days !! then i was happy

Most likely the battery is damaged, take it back from where you bought it and tell them your problem. Make sure you have STOCK software or else they won't repair it for you.
Only return it for repairs if you have warranty, if not, i suggest you to buy another battery.
Damaged batteries may damage the phone .

I never really cared about the "let the device charge for ## hours before operating" - and I never had any issues with battery life.
Well ... ok ... the only problem I ever had was that the battery of my Eee PC 900 died after just ~1.5 years (Windows showing "Your battery needs to be replaced") but that's another story entirely.
It may have an impact on the battery on the LONG run, but the problem you observe with your battery have another root cause.
Like I already wrote in the thread of yours, and others also recommended ...
Cause most likely is ...
- Battery dead (or you got a faulty battery back after the repair)
- Loading circuitry of the motherboard (which got replaced) malfunctioning
- Possible problem in the way you charge the phone (already wrote to you in a PM how to check and rule that out)
Take my suggestions I PM'd to you, maybe report back how it worked out, and if there was no resolve flash back to the Walkman ROM and send that damn phone off to SE.

[Q] Miscalibrated battery, need help!

I need some suggestions on how to calibrate the battery on my n4. It got miscalibrated when I did the update 4.2 to 4.3 and I haven't been able to calibrate it since then, a week ago.
I tried using battery calibration from the store but it didn't work, I tried charging the phone from 0 to 100 and it didn't work.
I remember I had the same problem 2 years ago with my Atrix and I solved it by wiping the battery stats from recovery, but now twrp and Cwm removed this feature and I don't know how to solve my problem.
Maybe it would help flashing all back to stock with the toolkit?
If you have any suggestions I'd really appreciate it.

Just the answer I didn't expected, and frankly a pretty useless answer, everybody knows that battery calibration doesn't improve battery life.
But I have other problems, like I turn off my device at 80% and when I turn it on it's at 77%. Do you think that's normal?

Either faulty battery or do the following:
1.Completley discharge N4
2.Charge fully(+2 hours after hitting 100&) WITHOUT disconnecting from the charger.
3.Repeat for better results.

To be honest, I don't know.
But if I would be you I would just let it charge while it's off(So the big ass white battery icon).
Let me know if you got your battery sorted after the method I posted!

You mean off as in all the way off? If so, then that ~3% is being used when the phone boots.

I've had many phones, and none of them lost charge during the boot, at least not that many. I think that's the clear sign of battery miscalibration, I've had this problem before with another phone. Besides that, I've had a strange behaviour of the battery, for example I saw it lose 4% in 1 second, from 66 to 62 in a blink of an eye.

It's not that it's losing charge quickly, it's just the OS (or the hardware itself) doesn't always do the best job of reading it. There's not much you can do about that, and it's really not an issue unless you make it so by staring at your battery level all day.

Hi,
I'm having a similar issue. Phone rebooting to weird battery levels (not the %age it shutdown at).
Phone shutting down at 31% battery and rebooting to 0%.
I tried charging only to 100% yesterday with the phone ON.
Do I have to charge it even after it's charged to 100%?

I tried charging through the night and then discharging it completely and charging it completely again. I also tried deleting the batterystats file (even though I know it doesn't do anything)
So what do you suggest I should do? Get the phone replaced or get the battery changed?
I live in India and the phone is from Canada, so replacing the phone will take some time but I can get the battery replaced for around $20
Also my nexus is also showing +ve mA values while it's not charging, and the values are absolutely crazy, +268, +168, +1171 (in batter monitor widget)
Please tell me what I should do.

Before you replace the battery try to disconnect the battery's flex cable and reconnect it [after you charge to device to 100% and turn it off of course] check if its 'reset' the battery.

i9500 huge battery problem

Hello everybody,
I have searched a lot on this forum, but I could not find this exact problem and I am getting very frustrated. I had this phone since mid September. The phone is not rooted.
Battery life was great for the first 3 months, than something weird started to happen. I also upgraded to 4.3, because I have the gear, but I do not think this is the main issue.
When the battery is fully charged, it drains more quickly than before and from my understandin looking around Internet, this could be because of 4.3. Ok, but it is not all.
When the battery reaches 40%, it starts draining super fast, like 15% per hour without doing anything. When it reaches 20% the phone becomes really hot and if I reboot it goes into a boot loop and battery goes instantly to 0%. If i plug in the chargher, it doesn't aknowledge it and does not charge. In order to fix it, I have to remove the battery and start charging. Now I can do it with phone on or off but the phone starts to charge super fast, definitively not normal. it goes from 0 to 10% in two minutes and keeps charghing super fast till it reaches about 50%, then it starts to cool off and charges more or less at a normal speed.
Today I unplug it when it reached 50% because I wanted to look at the battery SN, as I read there are faulty batteries starting with BD and mine does too. I tried to see if it is swalled, but it is hard to say without a good one to compare. Well, when I put the battery back in and turn the phone on, the indicator showed 80%!
I am very confused, as there are many factors involved. I read that 4.3 has some issues, I read there are faulty batteries, I read that many people tried to solve with calibration, but other people say it is useless on S4...
Would you mind sharing some thoughts?
Thank you very much!
I wanted to add my batter SN is BD1D606XX. According to this post http://forum.xda-developers.com/showthread.php?t=2504093
it shuldn't be faulty...

Change the battery. Batteries are cheap. Only tc dont buy again one with serial starting for BD :highfive:

Thanks for the quick answers. I live in Thailand, I bet all the batteries here comes from China and starts with BD. Are you positive it is the battery?

I was having the exact same issues and replacing battery solved everything. If you live near a Samsung service centre they should be able to do a swap for you with no bother. Samsung are aware of this issue and should not give you a battery with the same serial at the service centre. Obviously if you order a battery through a third-party supplier you will have to be a little more careful, but if you mention the issue at time of ordering you should be ok!
Best of luck :good::good:

Thank you. Yes, I live close to a Smsung service Center. I had already brought it in because it had stopped charghing, maybe USB ribbon. They fixed it in 1 day under warranty, so I will try to have the battery replaced under warranty. Worst case scenario, I will buy a new one, it is not expensive, but I want to find a different batch!!!

I could be wrong, but as far as I'm aware the faulty batteries only shipped in the boxes with the handsets :good:

battery drain super fast after 15 %

hi guys , i have galaxy s7 edge for a year and 3 months now , can someone help me please ?
the thing is from 100% to 15% the battery is super fine it endure like 20 h to 1 day of use , but once he hits 15% in matter of seconds the phone turns off
any solution please ? my phone isn't rooted

Welcome to XDA,
Li batteries suck when they are very high or very low. Between 100 and 90, it will drain fast too. This is a little fast though. How long has the problem been there for? Did anything happen around the onset?
Without a timeframe of the problem, my current recommendation: Try charging it to 100% and see if the problem persists. A full charge recalibrates the battery (dont believe other weird and wonderful ways of calibrating, google has confirmed them all to be false). If that doesnt work, it could be a battery or other hardware issue. If your phone is still under warranty, then you can let the Samsung guys look at it - maybe just a battery fault.

hi thank you for the respond , i had this problem for 1 week now and sadly the phone isn't under warranty anymore :/ well i tried the 100%charge method yesterday and now i'm waiting to see what will happen once it hit 15%

Let us know how it goes. If that doesnt work, then it sounds like it would be hardware related to me.
edit - I saw that a dude booted into safe mode and it solved the phone telling wrong percentages - maybe try that?
