So I had this 910C for a while. Still love this phone but recently the stand by time kept decreasing. This was my second battery but I used fast charging, so I thought what the heck, I will just buy a new one.
Well I did, and the stand by time is just as bad. Almost half my battery is gone by the morning, and the battery barely wants to charge as well. (it's like the phone is cold and the charger is also just lukewarm.)
So what the heck?
Is there a known hardware defect on the Note 4 for this?
Even if I could replace the phone (but why when it works great otherwise), I would still like to keep it around as a secondary device.
Any ideas?
Ps.: Now when I was writing this, my phone also got quite hot but the AUKEY portable charger is cold. My percentage was 16-17 and it could not go higher.
Well, after long hours of charge the new battery does show 100%, but when I make a call the phone gets extremely hot. Like it burns my face.
This morning I watched like 5 minutes of Netflix and that ate ~20% of my battery.
The battery does not get hot, is not bulked up, it's very hot around the main chip...
Using latest Samsung OS btw, don't even have root installed atm.

Hi guys, I recently decided to root my g1 with JF1.5 and I'm loving it so far. I did notice that it takes alot longer to charge the battery though. Is anyone else having this minor problem, and is there a fix?
thanks in advance for any imput
Battery Charge
I'm having the same trouble, and for whatever reason once it gets up to 95% it gets to 100% in under a minute, whereas as long as it took to charge it should be another 10 - 20 minutes. I'm not really worried about it though. Makes me think I have a really long battery life!
I'm not too worried either, as I have a car charger, but one of the things I admired about the G1 was how blazing fast it took to fully charge, and I miss it, is all.

and how blazing fast it took to drain completely.
Once you have it fully charged, let it fully run down once (i.e. until the phone turns itself off). This should allow your phone to relearn the battery's limits. Note that I do not recommend doing this much, as it may decrease your battery's life.
this topic's been covered on 2 other threads ive seen. However, i dont think anyone's come up w/ a solution yet, or a cause. I don't mind it so much since my phone will still last a little over a day w/ mild use before i would need to recharge it.
letting it run down completely and charging it fully doesn't fix it. neither does taking out the battery for a bit and putting it back.
I noticed that it took longer to recharge, but im not worried about it.
I noticed that if i reboot the phone while its charging the percentage raises dramatically, so if i am in need of recharging i normally hit a 3 finger salute while its charging.
I'm referring to the fact that the battery drains rapidly in the first few minutes, and might drain more rapidly than it should the rest of the day.
heres a post i made on another thread, but created a new topic also because i feel i really want to start a discussion about 2 different things:
1 my perceived odd battery charge cycle.
2 how many of us have this issue?
3 if not all of us have this issue then maybe there's hope i can swap this out for a different phone with out this issue.
here is my original post:
i do have something unique to add to this discussion but first:
well i can say that i did try this "top off" thing and it does seem to work, but as soon as i discharge the battery though use and recharge that night i was right back in the same boat of having a battery that drops very rapidly in the first 10 minutes or so and then continues to drop faster than it should the rest of the day. so imo, this top it off method only works at that moment, ie, not a long term fix.
also, i charged my evo battery in my touch pro2 and the charge didn't drop rapidly in the first few minutes. Also it seemed to last all day much better then it previously. i was able to play around all day with the phone and the battey drain was surprisingly good.
ok, the interesting thing i observed and i can replicate is:
when using the battery graph app i can watch battery level percentages versus time on a chart. in this chart i observed a charge cycle pattern that has me concerned.
while charging the percentage line on the graph was gradually increasing at a semi steady rate from 0% till 90%, then changed its charge rate at 90%
here is how it broke down.
0% 114am
90% 309am steady increase all the way to 90%
100% 315am very rapid charge at this stage (probably not good)
basically it had a steady charge rate of .78% per minute until it hit 90%.
then the remaining 10% rate was: 2.5% per minute.
this last 10% of the charge cycle charges 3.2 times faster rate then the previous 90%. i don't know much about charging but this may be a hint to something that's causing this issue.
also, just how many of us have this issue? all of us, whether we know it or not?
some of use? will there be a fix? is this covered by a warranty or software fix, or so we need to "top it off" every charge?
i'm still within my 30 days and i dont want to swap this out for another if they all have this issue.
I think its the way evo charges the battery.. As I posted about my findinga that when charged in my tp2 I dont see this fast drop anymore. The drop I saw was a 1/8 of the battery icon within 15 min not using.. So more than 10% drainage.. Also its nice the tp2 battery is the same.. So I always have a charged battery so I just switch out batts.. Most of use have this prob unless rooted and tweeked with setcpu..
Edit: only charge batteries from tp2 not from evo anymore..
sent from my Evo
I have read that this is the way the Evo is supposed to work. The battery charges to 100%, then it quits charging and runs off of the battery until it reaches approximately 90% charge, Then starts charging again. This is supposed to be better for the battery. So, if you take it off of the charger when it is about ready to start charging again, it can drop 10% in the first 5 minutes.
Franky, it appears to work this way with my phone, but I have not had the rapid battery drain issues that some have. My battery regularly makes it through the day fine with moderate to heavy use.
Another thing I have noticed is that not messing with it helps a lot. After I upgrade my rom it seems to take about three days for the battery to get back to its normal cycle. for the first day it drains faster than normal, but last longer each day thereafter.
i have done the same thing with using the touch pro 2 to charge my evo battery. kinda rediculas dont ya think?
that sure makes for an expensive charger, i would much rather sell my touch pro 2 to offset some of the cost for early termination what not.
i talked to customer support and of course their response was the canned response of "your evo is power hungery thats all...yada yada"
do you think that all evo's have this issue and no one else is noticing?
What I find funny is you buy a heavy use device that is designed for using. Everything you do on this device uses battery. I went from the touch pro 2 to this device and I am happier with the EVO than I was with the tp2. You might be surprise how much battery life you would get if you turn off all the radios except for the phone portion and only us this as a phone.
After the touch, mogul, touch pro, and tp2, I am permanently an HTC customer.
Sorry, just my opinion. I may be wrong.
Sent from my Sprint EVO 4g with the XDA app!
The bad thing is not all of us have an extra touch pro 2 lying around to charge our evo.
When I leave my phone on the charger and not use it at all and it drains 10% in 6 minutes that's rediculous. even though my phone has technically been in standby mode and using the battery for the top 10% their hasn't been one time where I took my phone off the charger and it didnt drop in 5 minutes.
Mine is random. Some days I get great battery life, and others I get 5 hours. I'm going having two spare batteries and a wall charger will fix this.

Maybe I gave too much info and perhaps I drowned my main point
The charging algorithm changes The speed in which it charges the battery at the last 10% of the charge.
This is probably the problem.
My tilt 2 does not do this. Therefore I get a proper charge and the charge lasts as it should.
Look at my findings above.
Hi guys,
Does anyone have any idea to this WEIRD issue I've had with my Desire Z?
Basically, my phone was working normally last night. I then put my phone on to charge as normal before I went to bed, and I left it on the bed. About 5-6 hours later (I had to get up early today...) I turned over and touched the back of the phone and woke up shocked, as the back of the phone BURNED me! I got very confused and looked at the phone. It was VERY hot to hold, and it was on 42% battery. I then took the battery out, and it was almost hot enough to burn me. I left the battery out of the phone until I got up properly and tried turning it back on, and it got very hot, very fast.
I figured it could be a problem with the 1800 mAh Mugen battery I was using, so I decided to put my old stock HTC battery in. I got the same problem.
It seems to have got slightly better now, but I can only really use the phone in 5-10 minute bursts now. When the phone has booted up the battery will report around 36 degrees. After 5-10 minutes it sails up to about 50 degrees before I turn it off. The battery also drops off fast between reboots, losing around 10% each time I reboot (however, it doesn't seem to drop that fast when I'm actually using the phone...).
I am rooted and using Cyanogen Mod 7, and I recently flashed to the 151 nightly. I tried flashing to some of the earlier nightlies I still had on the phone, but the issue is exactly the same.
I did have the phone in the bootloader for a while (volume down+trackball), and it didn't seem to overheat. However, when I tried charging the phone with the device off the battery seemed to get VERY hot (way more hot than normal).
Luckily I can still back up anything I need to back up, and I am going to start doing wipes soon (assuming the phone doesn't overheat while wiping, which worries me!), but I am very confused!
I'm thinking that some sort of short circuit has happened, or something?
Does anyone have any ideas? If it's a definite hardware problem I can get a replacement fairly easily, but I do love my Z, so it's the last thing I want to do...
Very lucky my dad has a Samsung Galaxy Tab I can borrow as a phone for now. It will be fun for a day or two having a 7" tablet as a phone, but it will get old fast!
Thanks a lot, all!
Edit: I think it's had it. I tried using another charger and another USB cable and leaving it charge for a bit. When I came back after about 15 mins, again the phone was very hot, and the indicator light was flashing green and orange. When I tried to boot the phone it was dead. When I plugged it back in the indicator light would flash orange on and off for a while, then start blinking weirdly. Lucky my mugen battery still has about 15% charge... xD

It's *possibly* this problem.
My phone does the same thing, gets SUPER hot when charging, and has extremely short battery life.
Mine's not charging at all now, so I'm not even sure what to do at all :/
If I use the phone a lil and my Mugen battery dies, I won't be able to turn it on at all, so I'm not sure whether to start wiping and stuff now...
General consensus is to not leave the phone to charge overnight?
not with today's technology. all batteries (atleast good ones) have an internal circuit that keeps the battery from over charging. it also provides a method to maintain the charge by letting the phone drain some battery over the night by 5-10% then performing a trickle charge to slowly (very slowly) recharge the battery.
I've been leaving my stuff charging overnight for over a decade. It's not as bad as you think it is.
The phone was great, didnt regret upgrading at all because I was getting great battery life. I have a lifeproof case, used wireless fast charging to keep my battery between 35% and 80% to prevent any battery damage, never had any heat or quick discharging at all. If I set it down while I slept, the battery might lose 4% in 8 hours... Boom, all of that changed yesterday. If I'm using it, it gets hot and the battery drains fast, if I'm not using it, the battery drains slower but still about 16% in 8 hours. If I put it on the charger it gets warm. I've powered it off and back on multiple times, I've turned off fast charging, it doesnt matter. Use or charging gets this thing all worked up somehow when before it played like a CHAMP. The wireless charging wasnt heating it before, i've only charged it to 100% once a week, never dischaged it below 15%. No new apps. Google play services has the highest power useage. Its acting like its got malware or something.
What should I do?

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
