Hello, i just want to give a testimony about my new Uni battery.
3 days ago I am buy a new battery for my TM MDA Pro. I buy this because I want to replace the 2-years old the original battery with brand new battery. Because the original battery is "damaged", the device blacks off when reach 38%, or 50% using UMTS radio, 80% using camera, 75% when using data connection. I am trying the troubleshooting rules posted by users on this forum but no effects.
Purchasing on the phone store, ask to the seller and they say they not have the Original battery, so the seller give me the second-quality one. I am comparing the original battery and the one which i will purchase. Different manufacture only. The original made in taiwan and the purchase one is made from China. Both from Dynapack.
after this all , i try it at my home. The new battery already filled but at 15%. Hey, if i am using the old battery one, i think the device cannot turn on. But with this new battery, it can switch on without turn off backlight or radio at startup. COOL!
And then I go to charge it until 100%. The battery is drained .. hmm little a bit quicker than the old battery, but It is very powerful, i still can use camera altough the battery at 50% ! Also i can use data connection when the battery at 15%.
So I think, buy a new battery is a solution if you have problems with the device that blacks off at XX%.
I just have this battery for 3 days, I will continuing testing this battery.
Note : sorry for my bad english
iam cheated........
even i was having battery problems die at xx%,i bought a made in china battery from a local shop.the time i inserted it battery was 45% left......but the battery backup was horribly low,in 15 mins my battery got to 15%....nd in next 10 mins it was fully drained......even if i havnt used any battery sucking apps,it was just in normal sleep mode,still it got drained,the original corrupted battery giving satisfactory backup despite of the turnoff issues....,i think iam cheated from that vendor......coz i bought it for a high price of 25$.and this f****ing performance is hurting me a lot......plz guide me guys what should i do.........
Sorry, there is something I forget to report, but mayur9890 has been remind me.
After initial charge until 100%, I carry it to my office. When on the road it still 100%. But after I reach office, it goes 69% ??? So quick??!!
But i have try to continue use them. But the device still working although the battery remaining is just 12%.
So I think I just have the "same" quality battery. Maybe the lost 31% on the new battery is same as 38% the old battery as that turned off. Hahaha...
mayur9890, the battery you buy is so expensive. I just buy around $15. With note my country is Indonesia.
Are the battery what do you buy is little same with the original battery? My old and new battery does not have significant differences. Just the manufacturer country. My new battery is from China also. From Dynapack.
I suggest you to buy that battery.
Thanks.

Man go back to the local shop and tell them the battery is faulty.. simple is that..
hello everyone, I'm a new note owner, I bought it used and I think it has two years on it, but it is in great shape. I noticed however, that the battery life isn't that amazing as people have told me, this coming from a Galaxy alpha user. I will leave screenshots of today's battery life and I think it isn't that amazing what it got
I've heard about battery miscalibration, is this really a thing? I can try and calibrated but I need to root it, & I wasn't really looking forward to reading it, since its lollipop on stock rom.
The screenshots are bellow of screen on time and total time, you can see that it's not consistent and I charge my phone two times a day.

I'm using lollipop official rom flashed on Odin via download mode, yes the rom is compatible with my country's frequencies so there's not really a problem there.
I notice however that the battery sort of goes down faster sometimes more than others, sometimes even going as far as draining 10% simply being on stand-by with LTE enabled for 2 hours in my pocket when I'm in class.
Is this normal behavior?
I don't think there is any such thing called miscalibration, I mean I am not sure, but well.
If your phone is 2 years old, then I think the battery has seen its life, time to get a new one mate.
Battery recalibrates itself .
However as the battery is old then Drain the battery to 5% power off charge fully unplug wait one hour top up charge and use .
Next step is new battery Anker brand is good .
Wiping battery stats/ supposed calibration has nothing to do with battery calibration and will make no difference .
Lithium-ion batteries last about 300-500 charging cycles, after that the risk of it dying increases exponentially. Some last 5 years, some 1. It depends on usage and environmental factors.
There is no such thing as recalibrating a modern lithium ion battery. It doesn't have a memory.
New battery costs about 20 quid, it should solve the problem.
Also, did you do a reset after the update? Updates can cause battery drain too, quite often.

No, I did not do a reset after the update. But I noticed this before updating to lollipop, I had to do some running around before I got home the day I bought it, and it was running KitKat 4.4. I got it with 93% of battery, walked home for a bit and was down to 65, went to the shopping and back, got home with 40 to 35%. (I bought the phone at around 5 pm and finally got home after going to the mall at around 8pm)

Then it's the battery, most likely.
Hi!
I have an old motorola defy phone, I really loved it when I bought. Now, I revived this phone, and bought an 1700mAh battery to it from ebay, and a new touch screen (previous was broken).
This one is the battery: http://www.amazon.com/Dream-Quality-Battery-Motorola-Photon/dp/B00Z5C0256
I've also installed a custom rom to it, Cyanogen Mod: 11-20140923-NIGHTLY-mb526
This is an android 4.4.4 with kernel 2.6.32.9-AeroKernel [email protected]omain #66, Sun Sep 28 01:07:03 OMST 2014
Yesterday I've fully recharged it, for 7-8 hours. I plugged out from the charger, and the status of the battery goes down extremely fast. It droped a percent in every minutes.
I was very sad, and I just put the phone into my bag. I went home, slepp one, and today morning I realized, my phone is alive!
It says, the state of battery is 1%, but it works since 17:30+ hours without charger. I am using it only for playing ingress, so only WiFi is turned on, and the App.
So, it seems, the state of battery is not the real state. What can cause this issue, is it the old phone, maybe the custom rom, or this remanufactured battery replacement?
And of course, how can I fix it?
I bought this phone from a friend, he warned me the battery life is horrible and that hes replaced it twice already.
Factory reset after purchase, wasnt too bad, ive seen worse. This week though it started what I feared. Today lost 40% battery while at work, never touched it once, no apps running, restarted before leaving the house. I even kept the sensor covered so no 2nd screen, but 6 hours of not being used, not even a call or text, I pick it up and see 60% remaining...
I'll buy a new phone before i buy 10 batteries.
Suggestions much appreciated!

Root if possible and use a custom kernel, should help battery life significantly

Replace the battery! Look through the battery threads in the "accessories" section for suggestions.
My V20 has terrible battery life also, sadly. Now I am using the Mi Max 3 which I only have to plug in once a week. I bought a spare OEM battery for my V20 and the battery never charged. I love the V20 for it's camera and the quad DAC. I can't use it as a daily driver tho due to battery going flat rather rapidly and it can't be rooted to test kernels.
I had terrible battery life and thought it was one of my batteries as i have 2, but it turns out that its the software i was running oreo but downgraded to Android 7 and the battery life is fantastic. I have tried custom roms but they are missing camera and fm radio apps which i use. Hopefully if we get Android pie it will have a better battery life.
