Boot loop after battery replacement - Huawei P9 Questions & Answers

Hi, I recently bought battery for huawei p9 on internet and replaced it. First 10 days, phone worked corectly except it reboot alone few times a day. After that, when i power on mobile, it just reboot every 2-3 seconds. Only can boot corectly when battery is 100% and when is plugged on charger. If I plugg off charger, mobile turn off.
Is this problem with battery or something else ?
Thanks.

Most probably the battery

Get another battery

Get another battery. Those are the tell-tale signs of an refurbished / aftermarket battery. Try getting an original new one if you can.

Moto G xt1069 dead after discharge batery!

hello everyone!
i have a big problem with my MotoG (xt1069).
At about 5 days it was working normally, however when discharged he not charged more.
Put another battery and did not work but his battery ran into another motoG.
I tried to put into recovery mode, but he did not enter.
Could someone help me?
It may be due to wrong battery calibration. Try to connect your phone to charger for 5-6 hours and then turn on the mobile. If it works charge the mobile only after the remaining charge become less than 15 ℅ repeat the same for three times
You could also try to hold power and volume down for 2 minuets. Do you get a white screen with a battery?

Xperia Z not charging after battery replacement

I have recently replaced my Xperia Z C6602 battery, the guy at the store told me that i have to plug the phone on a wall socket charger for at least 24 hours sometimes it even takes 3 days in order to start charging because the battery was flat, I didn't believe him tho until I've read some facts about waking up a flat battery, so I did what he told me and now for more than 40 hours, red LED is on and the Sony logo is flashing over and over in a loop, but the phone is not turning on. However I tried different chargers also I tried to force restart/shutdown by pressing power+vol+ thought the device is vibrating 1 then 3 times simultaneously but this didn't make any change, It's worth mentioning that my phone is unlocked and it was running a custom ROM (MIUI 6), also the device is getting recognized by the computer, and fast boot and flashmode are working fine, so I did successfully flash the stock firmware (10.5.1.A.0.283) using flash tool but this didn't fix the issue and the device kept doing the same thing over and over...
I just want to know if the fact about waking up a flat battery is true and the repairman was right about doing this process, or the new battery was simply damaged so I have to change it again.
Sorry for the bump but I'm in exactly the same boat. Bought a new battery from Replace Base Ltd for my C6603. When I connect the charger the phone keeps trying to start up then dies immediately. Running stock 5.1.1.
my C6603 battery was replaced 6 month ago, by myself..
yes, I bought a new original battery and replace it by myself
I only charge this new battery for 4 hours with EP800
now it's still working
maybe you have a faulty battery..

After reading a bit more about Li-ion batteries I would bet the new battery I bought has not been used for such a long time that it has gone into 'sleep mode' to prevent over-discharging.

Nexus 6 only turns on when is connected to the charger if not, shuts off

My nexus device only turns on when is connected to the charger, it shuts off whenever not plugged in.
Some weeks ago i noticed my nexus was randomnly shutting down at 15-21% battery then it got worse now at 55-60% of battery, one week later it came at the point that at 90% of battery shut down and have to charge it again and finally now it shuts off whenever not plugged in. I read in many forums about similar problems and tried a few "solutions" like Entering in bootloader then bootloader logs pressing 10 seconds the power button after this process this should reset the battery statistics and boot the phone but it didn't work, Factory reset, calibrating the battery and others but no one of this worked. What could be the problem?
Also in the bootloader it shows a message that indicates the state of the battery is OK
Your battery is shot

Battery looks dead, yup
You can find new ones on ebay for 30$~ (maybe even less) and start a brand new life

Don't buy cheap Chinese battery as 1) too much work to change battery, 2) swollen battery can break your Nexus 6, 3) cheap battery may only last 1-2 months before swelling
[UPDATE] I buyed a original Nexus 6 battery and replaced it with the old one, all seems to be okay, it solved the problem, but i have to test it to give a final answer i Will come back after a few months to let all the comunity and further viewers to know what happened

Battery problems - shut down with 40% battery

Hello Guys,
Well... I didn't have problems with my P9 around 1 and half year, but since last week I have problems with the battery, when it's around 40% it shuts down inmediatlly, a message " your phone will automaticaly shut down because of the battery low", the battery goes from 40 %to 1% automatically. When I turn it on again the battery is around 15%, but again it goes down 1% and it shuts down. When I connect my device to the energy the screen it shows is 40% and then I can turn on the phone again.
I don't know if the problem is the battery or the software.
Thanks for reading.
Sorry for my bad english.
Replace your battery and problem will be fixed. In other words your battery is not good anymore
Had the same thing. I took the phone to Huawei service and they replaced it for free and you get new LCD panel as a bonus

Hey, they replaced your screen, too? I sent my phone under warranty and they replaced the battery and the screen. I thought they broke it during the installation.

Yes, they told me that the battery is sealed to the front part with the screen and they replace it all together. Nice bonus, as almost after 2 years I have new phone for free .
Apparently there was a problem with their battery at some point so they replace it without any problems.

Hi, since I have the same battery prob and thinking about a replacement, too:
Is it necessary to reset the phone to original rom and locked bootloader to get a free replacement by Huawei service point? I'm currently on Moonlight with unlocked bootloader and twrp installed. So I wonder, if this matters (from Huawei side).

I would do that as custom ROM may be the reason for warranty void.

Along the same lines, I have a weird case: A rooted P9 lite (vns-L22c636b120) has the 50% to 1% battery problem. The odd thing is, it continued after I replaced its battery.
For example, yesterday I charged it to 100%. Unplugged from the charger, left it on for hours and it slowly went down to 96% -- good!
Then I turned it off - it rebooted.. Maybe I clicked the power button once too many times. When it came back up it said, warning, battery is at 1% shutting down. Tried rebooting, but it just turns itself off.
I charged it overnight.
This morning I turned it on and it was at 1% and shut down. I plugged it in, and in 10 minutes it said 20% full, and in 20 minutes it was at 100% (!) that's too fast.
What I have tried so far:
* Replaced the battery
* Replaced the OS - it won't accept anything over L22c636b130 it seems however - it even won't boot OpenKirin stuff - goes into boot loop.
* Re-flashed most partitions with stock ROM: boot, system, recovery, recovery2..
* Wiped cache/factory reset from recovery countless times.
* Followed Huawei's battery re-training method (turn it on, charge, turn it off, etc)
* Installed a few apps for battery calibration which claim to have finished successfully.
It's very baffling! I have no idea even if this is hardware or software.
Any ideas?

MI mix battery issue?

Hello guys, really bummed out here.
I recently rediscovered my original mi mix which I had 4 years ago.
Everything was working except the battery couldn't hold a charge. It will charge to 100% and while using the phone it will just shut down randomly. So I changed to a new battery and hoped for the best.
Now with the new battery it's the same. Battery charges up to 100%.i tried the pixel rom, xiomi global rom and now I'm on dotOS, same ****.
The weird thing is I put it in safe mode and the phone has not shut down for 4 hours now but it is stuck at 70%.
If I plug in the cable the phone works fine. The moment I take it out and start using it. It randomly goes into a bootloop and dies. When I charge it back, battery always starts of at 50%
Is there any hope or is it just a beautiful paperweight?

Hi Bro. I sent it to a phone repair shop and they said the issue was with the battery. Replaced a new one and its working like normal again. I probably bought a defective battery
Sounds like a mobo issue.
Try a hard reset ie disconnect the battery.
