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!

Universal suddenly shuts down; battery or other problem?

I recently acquired a HTC Universal for dirt cheap, and have found the first problem to explain the low price: Whenever I'm using a "power-hungry" application (TCPMP, Internet via Wi-Fi) it eventually just blacks out. Full shutdown without warning.
When trying to reactivate the unit, it reboots as if after a soft reset.
In fact, if I try to reactivate it too quickly, even the reboot fails.
None of the above happens when on external power.
This leads me to think that it's nothing worse than a battery that's lost its mojo, but since there is no warning about low battery, and when the reboot finishes successfully even SPB says the battery is somewhere around 70%, I want to run this by you guys.
What do you think? Just go get a new battery, or is there something else going on which will make buying a new battery just a waste of money?

I'd say it's the battery, 99% sure.
I'ts gotten old and its voltage breaks down under load. If you have proper equipment and a glimpse of an idea what you're doing you should drain about 300mA from the battery and measure its output voltage.
You'll most likely see it going below 3.0V quickly.

I'm afraid I don't have that equipment, but all I really needed to hear was that it's probably the battery.
Now I can stop thinking about it and just order a new batery.

Unexpected reboot - Apparently bettery issue
Hey Holybear, my device shows exactly same symptom, If possible let us know if bat replacement solved the issue>

I knew I wasn't the only one withthat problem. I think i've prooved it to be a battery faultt. as if you taake te battery out after it gets to that stage where you just can not get it too complete a boot up without it shuttinng down again
take out battery ,place finer oveer all battery trmminals and plug inn your mainss charger it should now boot up and runn fin off the charger unless your finger slips off the battery terminals. thisshsowws it's the temprature sensor in the battery.
I posted a more in depth reply to a guy in the wm6 threads as wifi heeaating up battery wass shutting off his device as well

@ cyberjak
Hmm, the idea that a temperature sensor in the battery causes this problems is interesting. I'd just expect the device not being cappable of rebooting instantly, because there should be a hysteresis implemented in the battery's protection circuit.
I had the exact same problems and described them elsewhere, but in my case it surely wasn't an issue of temperature.
I'd suggest to take out the battery and wait about an hour for the device and the battery to cool off. Most likely the battery will then take a complete boot but shut down soon after that - without having gotten near to "warm" yet.
If this happens you can be sure that the battery itself is dead without needing to measure anything.

Okay, to tell you what I tried:
I ran the Universal until it spontaneously went dead.
Started bootlaoder to see how much longer it would work on that. Was a bit longer, what with low energy consumption, but soon even that wouldn't stay on for long.
Then decided to try the "old wives' tale" (meaning I don't know whether there's any sense behind it or not) of putting the battery in the freezer for a little while.
When I took it out and let it get back to normal temp, I plugged it in and after a while booted the Universal. It showed 40% battery, lower than it had ever gotten lately.
Recharged for a full day.
Tried TCPMP: went dead after three minutes.
So in my experience the above didn't help battery performance.
Am going to get a new battery in a few days; I'll keep you posted on progress as I try with a fresh battery.

I had the same problem, whenever i did something cpu intensive, it would just black out.
I just bought a new 3100mAh battery. Best thing i ever did. It might be thicker now with the new battery, but it actually feels more comfortable as a phone. Plus the new battery only cost 13 odd quid, so definately well worth it. Oh and it doubles the battery life (3100/1500 = ~2... duh)
Hope that helps.

oh you know wat i have the same problem with my Jasjar and the bigest problem that there is no batteries on market for Jasjars in my country....its looks like im living in Jurassic Century!!!

If you want i can send you a battery xplayer, they're quite cheap here.

I ordered a regular battery replacement, but maybe I'll add a 3100mAh as well.
I could use it as a media player during long train trips.

I revived two batteries by intense cycling to work quite well again. They still black out at 20%, but only under extreme load (active gsm connection, active wifi, bluetooth and having to render a webpage).
But you should be able to discharge them below 25% at least. Else they're most certainly "too dead" already. And you should do at least 3-4 cycles.
My guess would be that the freezer finished your battery off. I don't understand how this method should work anyway, as lower temperatures reduce the time affected capacity loss. Actually the best place to store a LiPo or LIo battery is the fridge, charged about half the way.
But I also ordered two 3100mAh batteries. I'm using the Uni as a laptop replacement and the permanent wifi usage together with some cpu load and the backlight kicks the battery's ass quite hard.
In Germany the China 3100mAhs are overpriced and it's hard to get your hands on an external charger, but on Ebay.co.uk there's a seller that offers battery and charger as a bundle for about 15€. This will give me a solid 6000+mAh per day and should be enough to forget about virtually every setting related to power consumption
@ xplayer
If you haven't donw already, take a look at Ebay.com, co.uk etc and look if one of the sellers there will ship to kurdistan. You may be lucky

Thanx for helping the guy,yo folks on xda are the best

Just to give you all the end of the story:
I ordered a regular replacement and a 3200 mAh one, and both have returned my Universal to a well-used life.
Thanks again to everyone helping me out here.

For you guys does the device switch off only when the battery is low, or any time. Cause I have this problem as well, and I was SURE that it wasn't a battery problem until I read this thread. The phone switches off intermittently, sometimes after only 3' talk time right after it had been charging for a full 8 hours! Also, usually if I let it sit there for a few hours I could then turn it back on and it would last a full day, so I knew it wasn't due to low battery.
The overheating theory would explain my problem, as, now that I think about it, all my seemingly-random shutdowns were during radio activity (making or receiving calls, especially when the phone was searching for signal, or wifi, which would almost instantly kill it). Strange that it overheats like this, most phone batteries simply run out of charge faster and faster until they can't hold a charge at all, but mine lasts almost as long as it always lasted even though it's 2 years old - unless I get the shutdown thing of course.

I asked this in another thread, but since this one is full of people who got replacement batteries I'll repeat my question here as well:
How much thicker than the standard battery are the 3100 and the 4200mAh ones?

I also got this problem recently, so I bought a new battery and although it's only a 1600mAh battery it runs great again

hey roodkapje ive got that same problem with my battery for my spv m5000 the bad news is that i cant get that batery in barbados so im all out to see

does battery replacement fix lifetime/shutdown issues?

Hi Every one,
I've got the battery issue on my 6p 8.1. (fast drain and shutdown at 40 or 60%...)
I have found a shop who Can replace it with a new one.
Does the replacement fix this lifetime/fix this issue?
thanks,

Is the fast charging in cause of bad battery life? Is it advised to take a slow tradtionnal charger?

Awful.... I was outside with my son (Lost 30% with nous data ans light lin), I took only one photography... And phone died et 61%..
And impossible to reboot....
All my hopes are in the hands of the guy who will change my battery next monday.
(Lost 6% to write this message)

Accubattery estimates my battery at.... 22%.
I understand the shutdowns and Big drains...
Hope the replacement will be efficient.
My next charger will be a slow charger, it's said it's very bad for smartphone's batteries.

1-With your new battery the issue will be gone.I replace mine a few weeks ago and my Nexus 6P feels like a new phone.
2-Do not use any other charger.The best one so far ahead is the stock/original charger.

Did for me.

I left the US a few months ago for a long term gig here in mainland China. I brought my 6P with me. It was to the point that within 15 minutes coming off the charger at 100 percent, it would read around 50 percent and shut down. Took it to a Huawei service center here in Shenyang - they wouldn't touch it (claimed it wasn't a Huawei phone, it was a Google phone and I should take it to a Google store when I get back to the US. Talk about clueless (hey Charlie Chan.... what's that vendor mark on the back of the phone??). Anyway, ordered a new battery (cost me about 15 bucks US) and took it to one of the thousands of mom and pop shops that do cell phone service and had them replace the battery. Since then it's like I have a brand new phone. I'm getting usage of 6 - 8 hours of heavy use. I wake up in the mornings after forgetting to put it on the charger ... i'm still at 70 percent. It's awesome!

Had the battery replaced in January. No problem since then... As you said I think the problem is mainly the fast charge. Now I always use a normal charger and never had a problem since :good:

ok, thanks for advices.
Battery replacement is planned in few days.
Just hope it will be good quality, and have to find a slow charger.

Yes it does. Just make sure you get an OEM battery.
I did mine a few weeks ago, no issues with the install and no issues with the phone, and long battery life ever since.

Not possible for me to verify if OEM or not... (Will happen on a shop).
I will see how stands the new battery. I bring my phone tomorrow morning.
It coasts to me 50$.

back from the shop, job is done: I'v got a new abttery (for 50$).
Seems to be ok. big battery life.
The guy has broken the piece up in the back but will replace it for free.
now, have to buy a slow charger to take care of the battery.

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.

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.

how many have used aftermarket batteries with no issues?

I have 3 aftermarket batteries and over time have all showed the same issues. they may/may not boot, but even if they do, randomly for no reason whatsoever just turn off, like if I were to pull the battery out. it will boot but then keep bootlooping.
as soon as I put in the oem battery, its all fine.
how many have had this issue as well?

Not the same issues but I have a supposed OEM battery which boots but then then phone screen show “Invalid battery” and it shuts down. My V20 is the V995 Verizon model. The battery look the same as the original with the exception that on the top next to the contacts there is a small area, which on the original battery has a white spot, whereas the spare has nothing.

Same thing here with OEM batteries, it's rare but it's happened a couple of times after inserting a new battery. I just hit the power button again and it boots properly and works OK. My wild guess is maybe the battery didn't make proper contact? Dirty contact, maybe? Don't know, it never fails a second time and it's been weeks since the last failure so I'm not worrying about it and if your phone reboots OK after the error and shutdown, I wouldn't worry about it either.
Oh, FWIW, both my batteries have the white spot you mention.
Update, just did it again, hit the power button and rebooted with no problem. It's mildly annoying but not worth worrying about IMHO.

Hi
My battery still shows as "Invalid " on reboot, every time. Have ordered another and hopefully this one will be ok.

They were sold as official OEM but the markings on the back have small differences
I also have a zero lemon but it's no where near the quality of the others.

These days batteries lasts only two years. After that one day battery will stop working suddenly. This happened to my one plus one which was having normal battery but started rebooting suddenly one day. The service center guy said these modern batteries have some kind of kill switch which will trigger after a number of charging cycles.
The reason I bought lg v20 with an extra battery was to use it longer that two years.

I'm using this one since several months and had no issues. It took a few charges before getting my usual 4-hour SOT though. https://www.amazon.ca/Perfine-BCK-5200-BL-44E1F-Replacement-T-Mobile/dp/B06XTYCXJ5

I've had 6 different varieties of battery, including the IPossible 6600 (?) and the Li-Po. I've gotten the invalid battery message a couple of time but I just reboot and everything is fine. I've had the phone since 10\16 and I'll think about getting the LG V50 a year after it's released. I love this phone\Audio-God!

Still getting "Invalid battery" and shutdown, reboot and the same thing happens. Still waiting on my replacement due 18th. Original battery is now not lasting a full day but then I have had the V20 since Jan 2017. My main problem is that Amazon will not send batteries or liquid items to here in N. Ireland so have to try and source elsewhere.

I bought the Powerbear 3200 MAH, haven't received yet. but do you guys recon it's good?
