is it... the battery?!?!

I'm at a loss.
A week ago, phone started random resets and looping resets - usually when using a significant resource (i.e. camera, web).
I removed everything, reflashed rom, reflashed the Cingular rom etc. to no avail - same problem.
Today, I'm running the bare bones cingular rom without add ons. Seems like I'm doing fine - battery down to about 88% at 5pm which seems okay (I push mail from the exchange server). I take a picture with the camera and go to send it via email and the phone starts looping resets. I soft reset and I get a low battery message - 12%. I went from 88% to 12% in about two minutes.
Any expert opinions? Is it just the battery or is my phone turning into a brick?
Thank in advance.
Sincerely,
Jonathan

First off how old is the phone? It could be time to get a NEW battery.. these batteries have shelf lifes.. lol.. there days are numbered.

Phone is about 1.5 years old.

Update:
Interesting update:
Powered the phone off to pull the battery and check it out as I am looking for a new battery on ebay.
When I power the phone up, it now says battery is at 67%
- this makes me concerned that there is a hardware problem with the power management system in the phone...
thoughts?

"bump"
Any help, all. I would really appreciate your insight.

I'd start by buying a new battery. 1.5 years is a long time for a rechargable battery.

I am having the EXACT same problem.
I even bought an OEM Sanyo on eBay. No change. Then, I complained to Cingular and they replaced the phone (it took a LOT of complaining).
I put the new battery in the new phone, totally vanilla install. It worked great for a couple of hours, then the problems started happening again.
WTF? New phone, new battery and it's still happening.

Yeah - probably no way any level of complaining is going to score me a new phone from Cingular because of the age. I have a new battery on the way, but I am worried that it might be something with the charging circuit or something. Wish somebody with some expertise would speak up on this...

If you are lucky: they sell extended batteries on eBay. I bought me one for my TMO USA VARIO. The stand-by times are really amazing!
In case you consider to buy an extended one make sure that it comes with the battery door as pictured at the link below!
In general the prices on eBay are very low, so, if you are planning to keep your phone a bit longer you might want to buy 2 or 3 batteries at once? (Saves shipping and I really expect that the batteries will soon not be available any longer since the WIZ is discontinued.)

I had this problem. Looping reboots, might work for 5 minutes but then a constant cycle of reboots. Mine is a years and 2 months old.
I though it was the phone and was ready to ditch it. The battery showed a good charge.
I bought a OEM battery off of eBay for 10 bucks and the phone has not had one issue since.
No question it was the battery in my case.

Excellent. Thanks for the response. New battery was purchased last week and should be here soon, so I'll let you know how that turns out.
Might also take a look at the extended battery - seems like a neat feature, although it looks like it would keep the phone from fitting in my car stand (I use tomtom with it).
I'll post a reply when I find out if it is indeed the battery.
Thanks again.

Its a battery issue.
I had this problem before.
I would charge my phone using some 3rd party cradle and some how it screws my battery up.
for exmaple. The phone would say the battery is fully charged. but when i use it. the phone only lasts 5 mins.
after awhile. not matter how i charge the battery the battery never went to it's full charge. and like you, it keeps looping.
this was an OEM battery that i had for less then a year.
i got a random cheap battery off ebay to test it. and now it works fine.
i threw out the old battery.

UPSATE
UPDATE: It was..... the battery. Easy OEM replacement off ebay for less than 5 bucks. Running like a champ again. Thanks for the insight. Hopefully this helps someone else in the future.
Cheers!

[Q] shut down normally: now no power light or boot

I apologize in advance if there is a similar thread; I could not find one.
My EVO has been fine, no issues. I use it heavily every day. I'm running Cyanogen 7 nightly 147 (I think) and have been for 4 or 5 days. Using the Tiamat kernel running SMARTASS.
Last night I shut down around midnight with around 50% power. I plugged in the charger but don't remember if the charging light came on then. This morning there is no charging light and the phone won't boot. Tried long holding the power button, battery pulls, pulled the SD card (for lack of anything else to try). Nothing has had any effect.
Does anyone have other ideas? I'm at a loss. If it's dead, it sure chose a strange way to go. Any advice would be very appreciated. I need this thing for work and home. Many thanks.

Just after posting I went back to playing with different chargers and power button pushes. The white HTC logo flashed for a second and the phone vibrated but it went right back off. It's the first sign of life I've seen, but I can't get it to repeat or go further.

This happened to my sisters Evo when she first got it last summer. Luckily it was the battery and HTC shipped a new one for free. The warranty on the evo is 15 months so you can try and request a new battery!

I have found one similar thread: http://forum.xda-developers.com/showthread.php?t=913258. So maybe it is a dead battery. Been getting amazing life recently, so it seems crazy that it would suddenly be dead. Is this common?

Any suggestions for going to the Sprint store with a rooted phone? Since it's a bad battery, they may not need to look at the phone once it boots. I haven't had to do this before, so I'm not sure what to expect.

if you do go to a sprint store, i would not let them keep the phone or even take it out of your sight. if that happens you may well find yourself unrooted. but thats just a guess. you can get on ebay or any other similar site and buy a cheap battery for less than $5. then if thats not the problem go from there. this same problem happened to me but luckily one of my friends also has an EVO so i just used his battery and my phone worked great. so i just bought a new battery

Thanks for the input. Headed to the Sprint store in a minute to see if a battery will solve it.

It was the battery. They tested in at the Sprint store and pronounced it DOA. They said they don't normally have spare batteries but they happened to have one, luckily. I was pretty grabby with the phone and didn't let it go for long. Once it started to boot I took it back and they never saw the Cyanogen screens.
Overall they handled it very well. I was impressed with how responsive they were. I was out of there in 10 minutes.

random hardware issues? your battery might be going bad!

Hi everyone!
(TL;DR: i had hardware issues - overheating, slow mobile data, crappy battery life on 3G, non-responsiveness, etc. - that all got solved by replacing the battery for a new one)
I've been a faithful N1 user (briefly went to the nexus S, but came back) since april 2010, and my nexus one has been great ever since i got it.
A few months ago, I started having random hardware issues: first my camera led wouldn't turn on, then the speaker and vibrating motor went bad (I replaced all three parts with spares from ebay), and while i thought everything was repaired, I started having serious battery life and other random issues i couldn't really diagnose.
My phone would overheat after around 5 minutes with the screen on (i.e. while reading the morning news), 3G data was spotty and very slow, and the phone would sometimes be unresponsive for brief amounts of time. Also, my battery life dropped from lasting the whole day, to not even reaching 3PM. I managed to solve most of the issues by going 2G only - after all, I said, it's been almost 2 years and the phone was bound to go bad some time - however, the phone never really felt stable again.
In the meantime, I bought an OEM battery and a replacement digitizer (my battery stats blamed the screen for like 90% of battery consumption, so I guessed there was some sort of electric short on the digitizer or lcd, and the battery calibration app said my battery was only 84% fit), so I guessed I could try one last round of repairs before declaring my N1 retired. I even bought a Sensation in preparation to that sad moment.
Long story short, I swapped batteries 2 days ago and all my issues disappeared as if it was magic. Now I'm at 60% battery, with 3G on all day, and it's been 13 hours on, yesterday was similar. The phone has never overheated again since the battery replacement, and has been as responsive as I can remember, and mobile data has been somewhat faster (I blame my carrier for sucky speeds).
So, if you are experiencing weird hardware issues like mine, sudden changes in behaviour or just plain sucky battery life, it might mean it's time to get a replacement!! my battery lasted for about 2 years, and that's a very very good run.
Also, a bad battery was most probably the cause of the other components going bad, since i guess it didn't provide a stable supply of power.
Now I'm in love with my N1 again, and don't know what I'm gonna do with the Sensation I bought in desperation!!
Just sharing my story, maybe it can help somebody get their N1 back on full working condition.

Soooo agree!
I recently got my Nexus from my Dad. He blamed it for many things, included sudden reboot and overheating. I tried a bunch of GB roms, even stock (on which I even can't boot in with SIM on) and then I thought of the battery's fault.
As I can't find an OEM one, I just pick a new chinese battery, a SCUD 1420, the brand is kinda well-known as a decent battery replacement in town. Well, the battery life isn't that good, but now my phone hasn't reboot since then. Especially now when I run ICS, very smooth for an old N1
Still, could you tell me where did you get your battery please? I'm looking for an OEM that has better battery life.
Viva el N1

I bought from this seller on ebay. At least my unit looks ok (not exactly like the original battery that came with the phone, but very close).
it's also quite cheap, considering it revived my phone.
http://www.ebay.com/itm/33046584691...X:IT&_trksid=p3984.m1439.l2649#ht_1849wt_1189

mine gets a little overheat (debug mode even shows "overheating") when charging the original battery.
and since it was new, the touchscreen does not work if the screen is on for a long time while charging.
just got a new 3.2A/H battery, it haven't solved the touch screen the slightest
still not showing overheating though... but the original one showed even when it was new.

Problems with a new battery

Hi, guys. I recently bought a new battery for my 1+ two and after replacing it I've been having some problems. The battery life is actually lower than before and some times my phone suddenly turns off. Is there some way to calibrate or recalibrate a new battery or something I can do to fix this?

First of all, is your battery an official one or a third party battery? If its an official battery, check the manufacturing date. I'm not sure if oneplus is still producing/selling oneplus 2 batteries; it could be quite old. If its a third party battery, then I'd say its fake and of bad quality.

Yeah, I got one too. Manufacturing date is March 2017, and mine is also pretty bad. The turn-off thing happened once to me. But it really seems weaker than the original one. I thought that it needed time to go up to its full potential, but it's been 2 weeks and it's not good. Either we go back to the original battery or we go for a new phone.

Exactly the same problem. You are not alone. I went out yesterday and it just turned itself off and i couldn't turn it on . Didn't have a phone for 5 hours. And not only that MTP doesn't work (I'm not blaming the battery of course). It's not even showing as an unknown device in the device manager I wanted to perform a format, flashing an img via fastboot and I can't. #neveragain

Ok, so I bought a new battery because this one started to drop really fast. I got one from Ebay for $15 (last one was 30 from amazon) and it came really fast and visually it looks exactly like my original battery (the amazon one looked a bit different) only the manufacturing date is 03/2017. SO when I tried to remove the current battery, the connector got stuck to the socket. And I really tought that was going to be the end of this phone, but I removed it after some trying and put the new battery. Hope this one is better, if not I'll go for a new phone.

I recently bought a new battery from here:
https://www.replacebase.co.uk/oneplus-two-replacement-internal-battery-3300mah-fa-p597-original/
They claim its an 'OEM' battery, but its quite clearly a knockoff.
I also experienced some of the issues mentioned in this thread:
Phone powering off when fully charged (80-90% capacity) - and not powering on again until I plug into mains
Fast discharge - I'd struggle to get 12 hours out of a full charge, even with minimal screen-on time.
I'm not entirely sure whether the fast drain and phone powering off was related to the OS / Kernel I was using. For a long time I was using the lineage nightlies, recently I moved to Francos Kernel and also installed the flashable 'v3' zip from this thread: - https://forum.xda-developers.com/oneplus-2/general/power-tweaks-snapdragon-810-devices-t3261790 - which definitely looks to have reduced the idle drain and overall drain quite a lot. Also my phone no longer turns off randomly.
Additionally:
Removed all widgets
Turned off ambient display, turned brightness down
Turned off all gestures
Prevented facebook app from running in background - https://www.xda-developers.com/runinbackgroundsetter-restrict-background-processes/
I need to switch back to my original battery to see if I get better performance than the 'OEM' battery I bought - as potentially the battery drain issues I was having before were purely down to the software / kernel
edit: - still getting phone shutdowns with the 'OEM' replacement battery. Currently using https://www.cmxlog.com/14.1/oneplus2/#lineage-14.1-20170831-nightly-oneplus2-signed.zip and Franco Kernal r11

So what's dead / dying in my 6P

This happened to me today while browsing facebook.
My phone suddenly shut down. While trying to turn on, it would get to booting screen and then shut down again. It didn't loop - I had to try each time manually.
I cleared cache and reset it to factory settings to no avail. BUT once I got back home and managed to connect it to a charger (the battery was at estimated 90% capacity), everything runs smoothly. No shutdowns, no freezes - despite the phone getting warm. I stressed it quite a lot and it seems to hold, so I don't think this is related to the "bigger" CPU.
Could it possibly be a battery issue? Could my device be misreading the actual capacity of the battery?
As a sidenote: it did crash/shutdown once I disconnected the charger, but only after 20 minutes or so when I uninstalled a running at that time app.
Any feedback will be greatly appreciated, so I have something to work with and replace stuff accordingly - and hopefully not the entire phone, as I love my 6P.

It seems like it has to be connected to the battery, as it has been now holding (presumably) at 56% charge for over 4 (!) hours. AccuBattery shows the same data as what the phone reads, and now it seems that my power drain is in negative without charging the phone.
Sadly, there are no original replacements available in my country. Only cheap 3550mAh knockoffs that sellers call OEM. They do have Huawei logo, but everyone knows that 3450mAh is the only original capacity (right?)

Update: Nearly 20 hours on the same displayed 56% capacity.
Any help? Please?

No, you are wrong. Those 3550mAh batterys are the brand new ones from huawei. Those are the newest revision of the battery. Dont get the 3450 ones. If the seller is really selling a 3450mAh one, then its probably one of the old ones with the known issues.

Thanks for the heads-up. Just out of curiosity - how do you know that? When I contacted Huawei support, they did not answer me whether the 3550mah bat is a genuine product, or a farce. They avoided that question until they force-closed my support ticket without a proper answer.

First: Because i bought one and informed myself before. Then the new battery ran better then ever before. Even better then when the nexus 6p was new. Its the new batch that is better then ever before.
Second: you can read more about this topic in the correct forum thread about that: https://forum.xda-developers.com/showpost.php?p=78453441&postcount=1023
The thickness of the cable does not matter that much. Something you can care about is the weight. But this is something you can check when you got the new battery and also took the old one out.
To have longer battery life dont use the original charger. Use max a 5V 2A one. For example from a older Samsung mobile phone. Those have good electrical efficiency.

Thanks again.
For the 3 years I've bee using my 6P I never had battery life issues. In fact, even now the battery is holding well, despite the stats showing that my battery might be dying.
I came to this forum section looking for feedback on what could possibly be going on with my phone presenting the issues I am having. I am no mobile tech unlike many of guys around here. I might budge then and hope that the local Huawei repair center in my city will be of more help than the official Huawei support.
