Could it be Battery or WM6 problem?

Hey, I have bought myself a second-hand Universal and found it turn off at about 40% of battery. Could it be a software fault?

i have the same problem ( need help plz

i have the same problem ( need help plz

I'm pretty sure it's a battery issue. It has been reported numerous times, my Universal started turning off at ~35% battery after about one year, bought a new one, problem solved.

oh....
Maybe it is somehow recoverable?
I have no money for a new one... in my country they're quite expensive.

i have the same problem in wm5 and mw6

cycling the battery
You could try cycling the battery. Its probably LithiumION. You need to somehow drain it all the way down, then charge it up all the way a few times.
This should bring the battery back to full capacity. Only you can't do it on the phone cuz the phone shuts off at 40%.
That may or may not work. Typical life of a lithium Ion is only 2-3 years.
Ebay has really good deals on them for phones.

It is a battery issue.
Why don't you search a little.
There are some exact same threads already.
Buy a new battery!!!!

All well an good saying look at other threads and "buy a battery" but from my experience I am very sceptical about this issue. I have read many forums on other similar phones and it appears that the Exec seems to be the only model that seems to have this battery issue.
I cannot seriously believe that buying a new battery is the answer, there must be an underlying problem here which allways goes unanswered...!!!
I am now on my third battery, the last one lasted no more than four weeks when it started shutting down at around 75%, and this was a battery from the manufacturer...
My only other option now is to purchase a big blob of a thing which once fitted, will not allow my exec to sit in its cradle whilst on the move...

oh... these Universals seem quite problematic, but anyway I think i'll stay with one a little longer.
I think Universal needs too much power and this is why batteries, which loose some voltage after being drained, are so weak with it.
Some say that when they turn WiFi on, the battery faints at 80% I think it is caused because WiFi module takes even more power.

The problem is, Li-Ion batteries only last around 1000 dis-/charge-cycles. (see Wikipedia) and on WM6 I found no way to disable the charging while connected to my PC. (Okay, I didn't try another cable.) So every time you plug your device to your PC for some minutes, it's like charging your battery and it gets a bit weaker.
Also there's no memory-effect with Li-Ion-batteries so a full discharge followed by a full charge may not bring any results despite of an even worse capacity. You should only do this on the very first usage of the battery.
Wikipedia also says the capacity depends on the age of the battery. So if your dealer sells you a battery he has had in his shelf for 2 years, it won't have the capacity as a brand new one.
Read Wikipedia for more info on Li-Ion batteries. WM6 seems to consume some more power than WM5 and thus the battery shuts down a bit sooner than with WM5. It's really a battery issue.
If you could manage to charge the battery only when it is at around 10%, it will last longer than if you charge it every day or even on every PC connection.

AFAIK there is no problem to charge Li-Ion batteries every day even if it still has any level of charge exactly because there is no memory-effect.

from my experience - WM6 issue
reverted back to WM5 and now it happens at 20% rather than 40% previously with WM6.
try reverting back to WM5 to find if that is the same case for you as well.....

this ain't what HTC FAQ section says. That states the battery can be charged at any level withoyut any detriment to the battery life over a period of time.

How many of you had your edge plus shippdd with 0 % battery? Mine came switched off

Can i ask how many of you got your s6 edge + shipped to you with 0% battery? I have had 4 s6 edge + now the 1st one came with 0% battery shipped and next 2 came shipped with 60% battery and finally this one with 0% and switched off for months in amazon warehouse made in dec 2015.
Stupidly on of samsungs Vietnam manufacturing plants ships all their s6 edge plus with 0% battery i duno why they just do and i knew this when i saw the box. It has a diff sticker on imei from my 2nd and 3rd phone which was same batch different factory.
How many of you guys got yours with 0% battery and how has it affected your battery life over the year since release?
I hope there are some battery experts on here because im.in a mess i have to send back either my repaired one which i have now or this new 1 im.furious it came with 0% battery was switched off on its own and stored in amazon warehouse for up to a year. How much damage will that cause my battery long term?
Everywhere you read about batteries say dont let it drop to 0% and switch off on its own and dont let it stay like thst charge asap and dont let it happen too often.. so how.bad will my situation be?
0% battery less than 3.5V switched off for months at least 8 in low voltage state maybe 3.3V depends samsungs cut off protection circuit is set at does anyone know the voltage?
I use this new app called accubattery it's amazing it tells you battery capacity of your phone. Really amazing and it said the new phone had 90% capacity whereas my repaired one had 92% around 2750mah out of 3000mah. After a few days tho they are about the same.
My concern is will my new phone start to fail battery wise in a few months? I've asked battery experts online but cant get a clear cut answer just that dont let it drop to 2.5V as its dangerous but i dont know what effects letting it drop to potentially 3V will do. I mean when i plugged it in at 3% it was showing around 3550mv can the voltage really jump from 3V to 3.5V in 3 mins? I was using slow charger from s3.
Im tryna guestimate.what voltage it was stored at for 8 months to see if there was any permanent damage. I dont know but definitely being in storage caused me to only have 90% capacity out the box.
What complicates matters is package disabler pro wont let me use the old . version cos the note 7 fiasco has removed all options for Samsung bloatware i need so i feel stuck. I accidently uninstalled it on my repaired 1 not knowing i couldnt install the old version again.
Does anyone know what happens to a battery which is stored at less than 0% in a switched off state and is that worse than say consistently going up and down charging wise allowing it to switch off on its own consistently?

If you are shure that battery has been stored for 8 months without charge (0%), of course that battery has already some damages I mean, it hasn't all capacities of a new one. The worst things for lithium batteries is hi temperatures and be without any charge for long periods, cause the ions loose their signal or genre. So when they are at no charge, positive ones before can take negative charge now and negative ones before can take positive charge now. These ones will afect overall charge cause they came useless forever. Understand?

the theory of dont not let it drain to 0% seem to be a myth , which i recently find out after this note 7 fiasco after all these years , but leaving it totally drain at 0% for months is another issue , you managed to charge it ?

new battery dead?

Guys I need some help pls.
I ordered new battery, yesterday I opened phone carefully and replaced old battery, all went smooth.
But when try to switch on phone doesnt start. When connecting to psu it starts normally, battery shows 100% and not charging. If remove cable phone turns off instantly.
I wiped cache, dalvik, batterystats, no luck. Tried different psu, the same
I put old battery back and phone turns on and works ok, same as before.
Is possible that new battery coud be completely dead?
The new battery printed manufactured date is older than my current battery. 06-2015 vs 12-2015.
Is there anything else I should try , beside rma?
Thank you

Yes, there's a battery thread, where good replacements are linked. A 3 year old battery isn't a good replacement. Give it back to the seller. And did you try to put your "new battery" a second time in your phone, may you just didn't connect the cable correctly at first try. ???

Do search for " Cameron sino" for nexus 6p on either eBay or Amazon and buy that battery. I got mine for 25.00 . My phone charges to 100%, discharges slowly and doesn't shut off anymore at less than 20% battery like it did before. Accubattery app on playstore shows my battery health at 97% now ,the stock one was at 67% health. It does take a couple of full charges and full discharges to manage that health readout. Cameron sino seems to be the best one I've had so far. Just make sure you charge it to 100 and use it till it shuts off the first few times and profit. Trains the battery to fully charge and discharge . People make the mistake of charging when it isn't dead and that slowly suck the life out of your new batteries.

This might be true for nickel cadmium and nickel-metal hydride batteries , but it doesn't apply to lithium ion batteries. If anything, it's better to charge the battery when it still has ~20% left and stop charging around 80%. Lithium ion batteries don't like being too discharged or too charged as it causes them to wear out faster.

After quickly destroying the battery in my Galaxy Nexus I decided to research ways to prolong the life of the battery in my smartphone, especially since the phone I replaced it with (Nexus 6) didn't have a removable battery. So far they've worked great. Several tips I have are:
1. Plug in when you get to ~20-25%. If you want to be super extreme you can use an app like Battery Charge Limit to stop charging at 80%. Like I said earlier, discharging/charging too far is bad for the battery.
2. Don't use fast charging. This heats up the battery and wears it out faster. I've used the 1 amp charger from my Galaxy Nexus on my Nexus 6 and 6P and it has definitely helped prolong the life of the battery.
3. Don't use the phone while charging. This causes it to heat up and wears out the battery faster. Light things like texting or browsing XDA with their app won't heat it up too much, but gaming or installing ROMs while plugged in is very bad.
4. Don't charge the phone overnight while it's on. Obviously after the phone reaches full capacity it stops charging, but if your phone is on and running stuff in the background the battery will drain. When it drops to 98% it starts to trickle charge again until it reaches full capacity. This cycle of charging and draining will occur several times throughout the night and adds unnecessary wear cycles to the battery. It's best to charge while the phone is off to avoid this cycle.
5. Don't let the battery get too hot or too cold. Low temperatures can be just as harmful to batteries as high temperatures. If it's 100°F or 0°F outside and your battery is getting very hot or very cold it's best to just leave the phone in your pocket until you're in a place with a more reasonable temperature, such as inside a building or something. Lithium ion batteries prefer a happy medium, which is usually around room temperature (~68°F).
6. Keep the phone cool while doing CPU intensive tasks that cause it to heat up. When I install a ROM and boot it for the first time, wipe cache/dalvik after installing something, run the auto patcher in WakeBlock, or anything else that causes the CPU to run at a high frequency for prolonged periods of time I remove my phone from its case and place it in front of a fan on high speed. This keeps it from getting too hot, but doesn't let it get too cold. Placing your phone in the fridge/freezer will also keep it cool, but lets the battery get too cold, so that method is not recommend.
7. I use an app like EX Kernel Manager to display the battery/CPU temperatures in the notification area. If I notice the temperatures are getting too high or too low I stop using the phone until it cools down or I'm somewhere warmer. This can be annoying on Oreo because you get notifications of apps running in the background, but that's pretty easy to block
Keeping the phone cool can also help avoid the defect in the Snapdragon 810 that causes the BLOD (boot loop of death), which usually occurs when the solder holding the processor to the mother board develops cracks.
Based on posts I've seen in this forum most people begin to experience battery or boot loop issues after about a year or so. I've had my 6P for about a year and have not had any battery, heat, or boot loop issues. In my experience, taking care of your phone and being "extra nice" to it is the key to prolonging its life. After 2 years of using my Nexus 6, battery life on the day I sold it was just as good as day I unboxed it. I don't want to jinx myself, but the same goes for my 6P. After almost a year of use I can still go 16+ hours off the charger with 4+ hours of SOT and 30% or more left in the battery when I plug it in at night.

I'm gonna try this

One Plus 2 battery drain

Hello,
I am using One Plus 2 for a few years already. Lately I started suffering because of battery drain and long time charging. Problem is quite serious because while charging and using phone battery % is getting down. It takes whole night to charge it to 100% and in the midday I have 20% left.
I tried to use different chargers and cables. Didn't help.
Today I changed battery to new one. Didn't help.
Wiped out unofficial rom, installed official stock one. No addtional apps installed. Didn't help.
I am charging it with charge monitor app and while on AC charging I get very unstable charging graph. I need to turn off screen and leave phone untouched to charge it.
https: //zapodaj.net/21c02b80b986a.png.html
Where else to look for a reason?

Usually LTE connection drain the battery. Try disable it and try for few hours.

I tried to charge it with airplane mode. Didn't help neither.

Hi
Did you resolve your issue? I have same situation but I think that happened after when I do update Oxygen, now charger my battery is really slow and drain battery really quick. I can just leave, not touched my OP2 for all day and the battery after 8hrs got 30%. I buy original battery and still nothing change for better.

Hi
Have you tried to change the charging cable. I had the same issue and changed the charging cable. It worked for me.

Another problem is with a cable because original cables for OP2 can't buy anywhere right now, the company OnePlus has stopped production this cable for this device so I buy original cable Dash Charger from site oneplus.net

Three possibilities (at least):
* The charger is not working
* The cable is not working
* The battery is failing
Solutions for the first two are more obvious than the last one. Pick up a new or working used charger/cable. But the battery is a little dicier. And frankly, it is also more likely the cause for this than a bad cable or charger (esp. charger). But re the battery... No direct sales from Oneplus are available except via an official Oneplus repair job, which requires you sending your phone to them and them replacing the battery. Obnoxious, eh?!
The unofficial route? This is frowned on by many here, but not me. Buy a cheap ebay battery for the oneplus 2. Look for one that at least promises the battery's power matches the phone's specs. I bought one for $12 from an American seller (because I wanted a bit more accountability if it didn't work). They do work. They also take a while to start reporting their voltages and charges correctly, and must be charged / discharged completely a few times before things start getting accurate.
That's no official answer... just one guy's experience. Hope it helps.

Samsung Galaxy J5 2016 7.1.1 rooted Battery Replacement problem/ New battery problem

Hi guys, about a month ago accidentally I dropped my phone, when I picked it up it was a bit thicker than usually so I opened it and the battery was a bit swollen and one of the corners from above was broken imgur.c om/a/KMLiaG2 . I knew that the swollen batteries should be changed because the risk of getting on fire or explosion, so I bought a new battery from a Telekom Shop, the only shop with batteries from my city imgur.c om/a/GOCQktK . I noticed that the new battery made in china is suddenly draining fast when reaches 37% and dies when it reaches 30%. I did numerous battery calibrations, deleting batterystats.bin, letting it in charge over night, factory resetting my phone but it was useless. It was still dying at 30%. I was going back to that shop and they ordered a new battery to change the defective one. After 3 days it arrived and guess what, this battery is draining fast as well, when reaches 25% till 5% and dies. If I use my old battery it still working good. I can use it 6-7 hours with no problems, but the batteries made in china are keeping about 3-4 hours till it start to drain fast. What's the problem? My phone has become accustomed to the old battery? For real now, 2 new battery in row and both of them are defective? Also, I noticed today that the new battery was 20% while charging, so I restarted the phone and it was 52%. Also, how is possible that my phone with new battery shows that the apps that use my battery are only 50%? I know that about 15% is used by phone background, but what is using the rest of 35%? imgur.c om/a/DEvd4F what's the problem??

That's just typical of cheap batteries. Unless you order an original online than your wasting your time.
Look up other manufacturers aswel with a good reputation.
