Last night I used the wireless charger for the first time. Seemed to work great and had 100% when I woke up this morning.
It's about two hours later and I notice my battery is down to 55%. The phone is warmer than usual, two hours later as well. I haven't been doing anything special besides texting and some light Facebook.
For the last week I have been getting about 24 hours on one charge. The battery usage predicts I'll be out of juice after three hours.
I'm using this charger: PLESON Fast Wireless Charger Cell QI Fast Wireless Charging Pad Stand

I have the same battery life (around 40% remaining when I go to bed each night) whether I use the wired charger or my Tylt Vu wireless charger to charge my phone at night. Granted, the Tylt Vu only uses slow charging. But if your phone is fully charged, it shouldn't matter which type of charger you use.
My first priority would be to check for rogue battery draining apps.

Right. I've heard discussions of whether different ways of charging can affect total life of battery... LIke QuickCharge might be rougher on battery than slow charging.
But if a battery is charged, then it's charged. It won't deplete faster in one cycle depending on how it's charged.

Yes, makes sense. In my screen shot you can see my two highest battery drains. Is there another way to tell if an app is killing battery besides the list on the battery usage screen in the settings? The warmth of the phone even two hours after it was off the charger is a dead giveaway, but the app list was pretty sparse.
Thanks!

So, I'm not sure if anyone has this problem. I pull my phone off the charger in the morning when I wake up, and it's immediately at 96%. Is this a defect with my phone, or is it something I can fix?
Thanks
It's normal. It's actually better on the battery this way. There were some debates about the EVO and kernels that performed SBC charging.
This has been covered in another thread but here it is again...
HTC has used a new charging method on the e3d so it will charge to 100% then stop charging until it hits 95% at which point it will start charging again.

i use the battery monitoring widget.. it has a log that shows you the actual % of the battery while charging.. sometimes the phone will be displaying 100% while charging but in the logs you can see the battery is decreasing and not at 100%.
which is why when you pull it off the battery drops right away.
I'm glad I decided to search first, otherwise I would have the whole XDA community after me wanting to kill me.
Anyways, I have one of those notification icons that show me the battery percentage, but it NEVER reaches 100%. I am constantly checking it to see if I have reached 100% and nothing. Even when I leave it plugged it all night, it only gets to 99%.
I have also tried *#*#4636#*#* and it also shows 99%. Is this normal?
Your battery will technically never be at 100%. As even the most minute drain places it at 99%. Doubtful that HTC is that precise, I understand your frustration
Ok, but my evo 4g WOULD show 100%. That's why I was confused/worried when my 3D showed only 99% max.
This is a frustrating quirk with these phones. I also use battery monitor widget (love it BTW) and its pretty clear how the phone acts around a full charge. See below, graph of battery percentage overnight sitting on the charger.

If i happen to pull the phone off the charger when it is actually full (or as close to as it will get) then it seems like the battery really lasts much longer throughout the remainder of the day. If i pull it at say a 95% mark then it seems to be down to 80-85% by the time im out the door in the morning after a few emails / dickin around. If i pull it when its full then i only seem to lose a few percent, maybe up to as much as 5% by the time im out the door....
SBC kernel fix / help remedy any of these behaviors?
"Li-ion cannot absorb overcharge, and when fully charged the charge current must be cut off. A continuous trickle charge would cause plating of metallic lithium, and this could compromise safety. To minimize stress, keep the lithium-ion battery at the 4.20V/cell peak voltage as short a time as possible."
Don't panic, it's all as it should be. Don't try to outsmart your smartphone.
Recently they found that charging to a little less than 4.2V you get more charge/discharge cycles out of your battery.

Ok, here is my problem.
The battery indicator its stuck either at 100 % or 95%. I know my real batery life with a program (battery indicator pro).
It seems that the only way to charge it correctly is power it down and plug it to the charger (original by the way). If i charge it while is turned on, the indicator that signal the 100% charge never pops up.
I'm using the go launcher ex, its not rooted, and the stock rom (2.2.2 International).
PS:Yeah i know, my english is pretty bad, so please bear with me.
Mine gets stuck at 80%, both charging and discharging. After 3 or 4 hours at 80% it will go to 100% a few hours later. Hopefully they'll fix this on an update! The battery itself seems to be operating properly.
Well... I guess I take comfort in knowing that I am not the only one experiencing this odd bug. I have the exact behavior and like it's been said, my 5.0 player seems to have normal battery life. I just can't trust the charge indicator.
The method this device uses to estimate state of charge is VERY primitive.
It has a fixed table based purely on battery voltage - the problem is that battery voltage can vary quite a lot for a given state of charge depending on load.

I'm not sure why they didn't use the MAX17040 fuel gauge that is built into the MAX8998 PMIC...
mV readings seem more accurate than %:

mV readings are a poor estimate of state of charge, since they'll go up when on a charger, and down when under heavy load.
Our battery % indicator is derived directly from those mV readings. (Which is why our battery % estimate sucks.)
What IS odd is that you seem to have a case where the charger held flat at around 4060 mV for a while - which does correspond to an 80% reading. I think I've seen that once too, might be a kernel bug there, I need to look.
Showing 100% with the voltage dropping shouldn't have happened - I've never seen it myself.
I believe the "stuck" numbers are 80%, 100% and sometimes 65%. Happens every cycle for me, 80% being worst. But on a reboot, immediately drops 25-35% (depending how long it was stuck for). So if you reboot every hour, it will show good readings (but I reboot about once a month).
My tablets battery will say 100 then how down to 3% so ill turn it off then back on and it'll say like 35%. Then most recently its been stuck on 35-37% for some odd reason.
Did you guys try wiping the battery stats in CWM?
The problem:
Lately, well it's been quite a while actually... my battery stats seems to jump whether i'm charging or discharging.
While charging sometimes it jumps from 30% > 80% > 100% within 15 minutes (this is what happened today) while discharging, it jumps from 90 > 50 (this quite often) then to 20% > 5% then off. My max usage time without charging is usually less than 1 hour.
I've tried to do battery reset (charging while the phone is off until full, reset battery data, then use it till it 100% drained)
I've tried to charge from 30% to about 80/90% then use it as usual.
I used original charger from motorola, used blackberry charger, samsung charger, no difference.
Unfortunately no good. Currently the ad hoc solution is to use battery powerbank constantly while I'm not near electrical plug. But its bulky and well not the best solution.
My question is, does the problem lies in the battery or at the battery controller. Is there anyway to test where the culprit is?
Thanks in advance
Battery daemon Moto uses is imperfect in calculating the battery percentage.
However, the jumps you experience and the backup you're getting, looks like your battery has worn out.

Hi, thanks for the input. My question then, will replacing the battery help to solves the problem? Cos lately the battery stats seldom runs over an hour. Here's a screenshot of my latest battery stats...

Your battery is definitely worn out. Replace it.
A new battery will certainly remove the issues..
Use the 10% mod though else you might still have infrequent jumps..
my z5c came with regular 1.5a charger (which take to charge to 60% 60 minutes , and 75min to 80% 2.5hrs to 100%
i saw aukey QC 2.0 for about 14$
and charge to 60% is twice as fast(30mins) but to 100% is only 30min diffrent 120mins
is worth buying it?
thx
It's worth every penny and a must without a replaceable battery. It's the only way I could get my phone to last throughout the workday was to quick charge at lunch.
I wonder what you work that you have time to drain your battery so fast
when I leave the house at 6am and come home at 5pm I have about 75 to 85% left. When I go to bed at 11pm I still have about 50%. (and no Stamina mode etc) Maybe I'm not that kind of power-user...
Anyways. I bought a quick charger (Anker Power Port+ 1 and Power Drive+ 1 for car) to be prepared for situations where I need power very quick.
To OP: Quick chargers are not meant for charging full capacity in high speed but for charging a certain amount very quick, but the end goes slower. So when you have about 10% left and you're for example about to go out at night, then you can quick charge it to let's say 40 or 50% in a short time. So your battery will last the night at best. That's the main purpose of quick chargers.
I have aukey qc 2.0. To be honest it doesn't charge as fast as qualcomm says. But still it charges about 55% in first 30min phone charge to is less than 5%. From 0% to 100% it takes about 105-110min
Qualcomm has done test in laboratory condition, I think it means no WiFi no data almost 0 apps etc.

Emails,texts, calls, and a lot of data input to spreadsheets. My phone is screen on pretty heavily from 8am until 4pm.
This was a good day here lol I average about 5 hours of screen on time and see that's about the same for everyone, except my 5 hours are 5 straight hours and really need to be 8 or 9.

I just got the Realme GT 2 Pro after replacing my 3 year old Xiaomi one. I want to use this new phone for at least 5 years, and I've been learning ways to help the battery not die quickly. I've learned to charge the phone until 80% and I've been doing that for a week and a few days now. It does annoy me that the battery feels weak since I am missing 20% charge. I'm contemplating to just charge it normally, but on a 10W charger rather than the 65W charger it has. Should I continue charging it up to 80% or just use it normally?
20-80% is best but decay is inevitable
You could probably get AccA and set a charging cap.
https://github.com/MatteCarra/AccA
If you look at charging chart, the OS keeps battery at around 75% overnight

Down the road, replacing battery does not seem hard.

I cannot see the point of this, and with all respect I doubt this phone would be worth using after 5 years. More likely will not get any security updates by then and I dont think it will have much custom support either. On the other hand the manufacturers just sh1thing out 100s of phones a year, god knows what phones we would have in 5 years time, but for example I wouldn't want to use an old Sami S8 or 9 as my daily phone.
It is a good device and I like its battery life. I use it as a secondary phone therefore I share the battery usage with my other phone. In my usage I get a day and a half or 2 days out and would still have around 30-35% left. That's when I normally charge my phones, never let it discharge totally. I have seen in some articles that some experts don't recommend charging it over 80% due to the quicker wear of the battery. Honestly I cannot back this up.
There are a few things however what I can.
Do not charge when the phone is in use, like you have a long gaming session and you charge at the same time. The heat is the biggest enemy of the battery and charging and intensively using the phone at the same time could cause quicker wear out.
The second thing I never do is plug it up to charge overnight. With the quick charge tech this device has, its not even needed because its charges up in around 30mins for me. As soon as charged I disconnect. I noticed on my older iPhone when I charged it overnight, it caused quicker wear.
The above is my experience had over the years using several smartphones, but I hope it helps. Or just good luck using your GT2 pro in 5 years time
