Battery Instability

Nowadays I have a weird problem. Even though I fully charge my phone, it behaves like battery is empty. It happens in two way:
1. After some usage, it can occur at 15%.
2. While showing battery is charged enough, you restart the phone. It starts as ciritical battery level.
3. For case 1, it can happen at higher levels as well. Screen starts flickering then phone shutsdown suddenly.
I tried calibration apk. I suspect it caused some problem also.
My system was stock 4.1.2 leak. I thought it may be reason, so I downgraded to ICS. But, I still have same problem...
Any1 has an idea? Battery or phone has problem or not?

May be time to get a new battery

I opened back cover now. I am very surprised. Battery got deformed. Middle part became thicker. It cannot fit to battery slot.
I think god saved me. It could explode.
This turned from question to possible Samsung defect. So, I am agree originally I made wrong choice. But, this topic is suitable for here in the light of my new finding.

I have the exact same problem! Been wanting to change the battery but haven't found it. If you buy a new battery and everything comes back to normal, please let us know!

I have same issue as OP. My screen starts to flicker at 15% as if it's about to lose power any second.
Happens with OEM battery as well as two aftermarket hyperion batteries.

Same here.. my batterry was a little bulged at the middle and i thought it is still ok.. then it started acting up..
-It says fully charged on the battery indicator while turned off and charging
- when I turn it on, it says 50%..
- when I get to recovery (philZ stock kernel recovery) it says 1%
Then it got worse and wont turn on when unplugged... Bought a battery at our local samsung store and all the problems went away!

Awesome!! That's what I wanted to know! Now I'll look for the battery.
Does anybody know why this happens?

I had this issue last month. Changed to Mugen battery. Everything's good now.
All the symptoms described here are dying battery issues. Have them replaced before your note dies.

I was unaware of this situation and I downgraded by JellBean to first GB, then ICS. I am lucky it did not shutdown during firmware install.
I went to some official Samsung technical service. They will give me a new battery soon. I am using my Sony Ericsson Walkman series phone Luckily I have iPad with cellular. Now, I will just wait and I will hope everything will be ok.

I bought a 7000 mAh battery on ebay. It's awesome! No problem now. My battery last all day :good:

Mbuybow battery an its reliability

I found this battery here :
http://www.mbuynow.com/2500mah-rechargeable-battery-for-lg-optimus-4x-hd-p880-p-747.html
It is cheap and comes from the UK (maybe was build in China ?).
It should be 2500 mah with no extra space needed.
I'd like to know if someone bought it and if it's a good product.
I'm looking for a new battery for my phone without changing the back cover and I'd like that is reliable and does't create problems to my phone.
Should you buy it ?
Do you know some alternatives ?

mbuynow
I bought it about 1 month ago. Battery life is a little better than with original battery for me. It fits into the phone without problems.

so do you thing that is a good replacement for the original battery ?
no problems ? (like high temperature or other strange things).
I ask you so 'cause I paid my phone 410 euros and of O have to save only 10 euros but damaging my phone,i'll buy another original battery.

For me the best i had so far, and i have tried 3 different batterys. No problems, just loading seems to take longer, but it has to for longer battery life.
I didn't stop any times but if i should take a guess i think i have +2 hours on average use over the day compared to the original battery.

bentiger91 did you try also Akku Polar Cell? (http://forum.xda-developers.com/showthread.php?t=2431384&page=2)
If yes, which one is better in you opinion.

Hi guys.
I bought this battery few weeks ago and it was working just fine until yesterday. Suddenly I wasn't able to boot up the phone. It boots up, shows Enter pin screen and then starts to shutdown imidiatelly. At first I thought it was a problem with software, but it turned out the issue went away when I replaced the battery for stock.
Anybody else seen this before? It seems the phone refuses non-original battery.

Solved erratic battery issues

Like many others I was experiencing weird battery issues. It would jump 5% increments within seconds. I'd have 46% turn on a movie and 2 minutes later it would shut off. I tried every app fix in the play store as well as different kernels and ROMs. During this issue I broke the screen sent it in for repair and they said they'd fix the draw problem. All they did was Chang the data cable. I got it back and it was worse than before. Before I sent it in I ordered a replacement battery and decided as a last attempt to fix the problem I installed it. Believe it or not I'm now getting 8 hrs sot. I watch the battery meter expecting it to change but it stays on the same number for at least 15 minutes. Hers a screen shot of halfway through a cycle. Also when I go to sleep i wake up to find the battery meter is on the same number as when I went to sleep. Finally it seems all I needed was a new battery. Hope this helps others
Can't get the screenshot to load gets stuck on processing but these are the stats
50% used in 21h
Screen on time 4 hrs 6 minutes

Well congrats you got it fixed, too bad you had to spend your own money to buy a battery. You would think that would be covered under warranty?

I heard batteries are never covered. but I guess if you can prove it's defective from factory, they might change it.

I bought the tab online the battery I bought from batteryship.com for $35 comes with free toolkit which was awesome. They even have a walk through video on yt. B4 the most I'd get was 2.5 hrs sot now I'm getting over 8hrs I can't kill it videos gaming nothing. I know a lot of times batteries are just rebranded but its funny Samsung's OEM is crap and aftermarket is quality. IMO its definitely the battery.

Depending on the countries legislation, a manufacturer can't really decide a certain component isn't covered under warranty. If a device is warranted for 12months from defect then so are all of its components.

Samsung covers batteries but I think they know exactly what's causing this issue they just don't want to absorb the cost of changing out all these batteries.
Moto X 2014

The only thing that Samsung do not cover is loss of battery capacity - they do cover faulty batteries for 1 year.

How do you prove that the battery is faulty?
I have been getting erratic battery performance also, how do you prove that the battery is defective?

I was just having a look to price a battery for my T800, I found one on ebay uk at an amazing price with free shipping.

I just bought a Tab S 10.5 yesterday as a replacement for my Nexus 10 who's battery is almost useless. Right now you simply can't find N10 batteries so depending on how long you plan to hold onto your Tab S, buying a replacement now may be a good investment even if it is only used to increase its resale value down the road.

Battery Experts say that you should not buy extra li-ion battery`s that you are not going to use, like a spare battery that you alternate with the one that came with the phone, camera, ect.
As as soon as an li-ion battery comes off the production line it will start to age if it is used or not, so you might buy a replacement battery, and put it into storage and 3-5 years later you come to put it in your tablet, but find that 50% of the battery`s capacity has been lost.
If you really abuse your battery and it dies within 6 months to an year it might be worth buying an replacement then, but only if it`s a really really good never to be repeated price, or you are in a country that you cannot get a warranty repair.

How do you dial on a wifi tablet?

another battery problem
I have 2 tab s8.4 to play with.... mine was bronze my sister has the white one... both t705... on my tab i am not having any battery problem but with my sister At first it was having erratic battery issue... i opened it re attached the battery and problem fixed she had longer time to use the tab.. it could go on for more than 12 hrs.. now she used a power bank to charge her tab for only about 10-15 mins because she needed it and while we were eating out.. A day passed her tab is experiencing the similar erratic battery.. from 45% down to 20% then restared it 36%.. what seems to be the problem?? Should i reopen the tab?

The same issue is with my tab s 705. Battery goes to 4% from 100% in 25 mins. Shuts down & when restarted it show 74%, but again behaves the same way with different %. Mediaserver also runs a lot, i have not rooted tab s.

Try reattaching the battery and fully drain then fully charge it then ×#0228#... worked for me

I just returned my tablet for this same exact issue was playing Hearthstone on it after 35 days of having the device all of a sudden it was dropping from 100% to dead in 45 min. After it turned off I would turn it back on and it would be at 75% battery. It would then die in about 20-30 min again and when i turned it on it would be around 40% and so on and so on until it actually hit 0%.
Things I tried before I returned it:
- Full discharge and Charging while the device was on on a slow charge
- Full Discharge and slow charging while device off
- Battery Calibration
EDIT:Thing specific to my use.
- The device was ALWAYS charged with a 1amp anker backup battery/ charger over night
- The device was plugged in to a belkin quick charger 2amp most of the day while at work
- The device was always charged with a 2amp standard Samsung charger when at home and needed a cap off
I did not try the dial trick or opening the devices up because of how new it was. Can I ask why would using the ×#0228#... Do anything for the battery this seems to be a misreported battery capacity that is coming directly from the battery. I could see the reconnect doing something I just don't understand how ×#0228# could do anything for the issue being displayed.

This definitely seems to be a connection with battery, or calibration issue. I have no idea what that number does so... yeah. When you play a youtube video or some sort, does the battery drops still happen when just playing a video? The last thing I can think of is type that number in and see what happens. If the problem still persist, I'd suggest you take your tab back

Mine is already returned I am picking up the replacement in store today. I was with in my 45 day grace period wasn't going to go crazy with it. If I had seen the ×#0228# suggestion before returning it I would have done that to but I didn't. I hopped in this thread in the hopes of helping others who weren't as lucky as to be with in the grace period for return and repurchase brand new.
Not looking forward to re-customizing my tablet when I get it. No root(for warranty reasons i don't root till it expires......LIKE this one I am in now) = fun adding all the accounts back!

New battery, original or fake?

Hi,
Yesterday i buy new battery for my old lg g2, but i'm not sure is it original.
My New battery is non stepped like this http://tanstartrade.ca/images/LG%20BL-T7.jpg
Do you think that it could be authentic?
Thanks in advance for your help.

I just got replaced battery in service - they told me that they use original LG parts. When I checked it under the cover, it shows manufactured date 6th of January 2016. It is not allowed by antena strips and curved back cover to have thicker battery and thinner would have less capacity. You could probably try but I don't see any benefits in that.
EDIT: After few days of usage I had to get my battery replaced by the old one. May be bad luck with not properly working battery but more probably faik one (runs for 0-10 mins, weird force charging in no OS mode). When they showed me the "new" battery in service it is thinner than the original, does not have the stepped back and thus makes gap between back cover and battery itself - 2mm of medium hard press. So it was like yours - flat design - no additional stepped part. The service was not authorised service but looked legit and had plenty of good reviews. So it's my experience of flat lg battery replacement stated as original.

Be noticed that all of below information are not yet confirmed.
I discovered the difference between original and fake since searching trough forums and own experience. :victory:
Design od LG BL-T7 battery has not changed ever since. Still the only one with the stepped back side. Should look like the battery on right side of these pictures, otherwise it is nor factory replacement (aka fake):
http://i.imgur.com/2Yt8cvDh.jpg
http://i.imgur.com/hkVpceYh.jpg
http://i.imgur.com/XtEH5AQh.jpg
The main difference is in litle bulk under printing "BL-T7", arrows under the NOM icon and next right is noticeable differnce in T in that symbol, fonts differ and last letter of chineese behind the manufactured day,...
There is a believe that non-original batteries are not that bad at all, only they have poor wiring and connection port which often makes them behave unexpectedly.

I replaced my battery recently, they told me that it's not the original one, its a Chinese made but works well. So far, no issue.

Where did you get that one?

Note that if you face any issue regarding charging since these batteries are years old, then feel free to contact the seller and you will get a replacement.

I bought that same battery. It had no glue residue and the year was rubbed off.
It looks genuine but I won't be able to tell until my replacement screen arrives and I can install them both at the same time.

I bought a 3950mah high capacity battery from aliexpress (so clearly not geniune but for the money I decided to give it a shot). it works fine, got my Screen on time from 2-3h to 5h or more. However, when charging, it will charge up to 95-99% and then, while still plugged in, go down to 83% and stay there. Then when I unplug it and start using it, it first goes back up to 90-95% before going back down like normal. Has anyone experienced something like this and/or know a way to fix it? I tried some battery calibration methods but no luck. Also, since the phone rarely reaches 100% (indicated) it doesnt always reset the screen on timer properly... this makes it difficult to keep accurate track of its performance. when it does work 5h seems to be the usual value.

That one sounds weird.
Definitely not normal.
Only solution is to buy another and test it or return the one you haveDefinitely and try another one

I have contacted the seller but so far they are not replying... I tried the Ampere and 3C Battery monitor the check the voltages and currents while charging. At first, I thought the phone showed the wrong percentage as it was not calibrated for the high capacity (so 80% was actually 120% relative to the standard battery capacity) but it showed that the phone was actually discharging once it reached full charge. Also, my assumption of it being 120% was wrong since the percentage probably comes from the cell voltage. So, next I checked the cell voltage using both ampere and 3C but the values were all over the place, jumping from 4.36 to 4.2 and back. this made no sense. The battery has a top voltage of 4.37 when fully charged so maybe the battery monitoring software of the phone is confused by this?
In any case I will wait for the seller to get back to me and if the problem becomes worse I will get a new battery to test out.

Thanks for the update.
Keep us posted on how it goes.

Hello guys, I am looking to buy new battery for my 2 and half years old g2. So here are my options:
1) Pollarcell - they says it's great battery, but still kinda expensive for a non-oem battery. It would cost me about 25e.
2) OEM LG battery - in LG official service, I have to check it they still got them, price was about 30e if I recall correctly.
3) Some random battery - I guess this is lottery.I can get good or I can get bad battery. There are many brands, and their price is from 8-9 to 15e.
OEM is best choice for sure, but I don't feel like investing 1/3 of phone price in battery, especially cause I don't know how long I will keep that phone. Dunno what to do
Edit: Did anyone tried this battery? It has quite high rating
https://m.aliexpress.com/s/item/32572840069.html#autostay

Beware of Pollarcell batteries I have read cases of burning

Bought my new battery at PhonTrading24 ,
Battery is class and from new production 12/2016 .

fake or original?
I also changed my battery after 3 years at LG service however I have some questions in my mind whether battery is fake or original one. Although new battery has same capacity like old one but it doesn not last like new one ( it lasts almost a day ) Pictures are attached new and old one. What do you think guys?

It looks like the original one and it might well be. But that also means it is not new, as the production of original batteries have stopped several years back. So what you have is probably an unused but ageing battery.
Batteries start degrading the moment they are produced, just that it degrades at a slower rate being unused (depending on temperature it's stored etc), compared to it being actively used everyday.

thanks a lot for the comment. I have been using this battery for a month now and the battery ends after completing one day. As and old production not bad as you said.

New Battery - What procedures to be done?

Hey guys! So I am having now turning 3 years old Xiaomi Mi3. It is still working pretty good with all these roms we've got credit to the great developers we have at XDA. The only problem I'm having is with the battery life. Previously it would last whole day. Now I'm charging it thrice daily.
So I ordered a new battery and replaced it.
The problem is at around 20 % of the battery, the phone died suddenly and when I put it in charging it flashed the notification light as if the battery is completely drained. Mind it that after replacement, I straight away charged the battery to 100% and then calibrated using battery calibration app by Nema.
After the phone died, I put it in offline charging and didn't reboot the phone until it was totally charged and then rebooted. It is now working fine!
The battery is holding better than what I was having but still, it goes down easily.
I am a heavy user! Lots of browsing, ebooks, emails, whatsapp, camera, etc.
Is anything else needed to be done.?
I am currently on second battery cycle of the new battery. Right now I got 2 hours 10 min SOT and 45% still left.
I am pretty sure, even this is not going to last the whole day as it used to do once back when the phone was new!
BTW am on NOS and it is pretty stable and generally always on 3g.
Please advise!

If you got the battery from official service center only then expect it to work as it used to do when the phone was new. Batteries from eBay, amazon and other websites won't give backup as the original one does because they aren't original ones, typically such batteries have 60% backup when compared to original one.

The thing is that the service center guy tells me that they have stopped importing parts of Xiaomi Mi3. I tried it in another center, they told me that it will cost 1500Rs for the battery and 600Rs for installation and service charges.
So I got it from ebay at 300Rs and replaced myself.
Probably you are right and this won't be giving any improvement to me! I just gave it a try so that I can wait for a month or so for newer phone launches. But I guess I have to rely more on charger than on battery

got a new battery for 300₹ from ebay..replaced it myself..3 yrs is more than enough from a single battery..battery backup ki great..m getting around 4.5-5hrs of SOT..probably which i was getting when i bought this phone..currently on DU. i am on wifi almost all the time.

Can you post a link?Does the device shut off at 20% battery?
Also can you check the battery temperature while charging?The one I bought from ebay never goes above 25.
