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.

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

My SGP5 battery has been wacky since day one. First few days I didn't think it would charge past 80%, but I found if you charged it overnight it would hit 100% (that's after an 8 hour charge to 80%).
Today it showed 100% all day. I booted it and now shows 30%. The settings battery status does not show actual time on the lower scale. Like I said I was at 100% all day, and the chart goes up to a 100% peak, but doesn't flatten or go down.... as if the battery clock stopped (not there is such a thing).
Can't do a battery pull... could rooting solve this issue? At least you can do a calibration with root. I just don't want to root if this will be fixed in an update. But I really don't like not really knowing how much battery is left.
I have a similar issue. It seems random- I use it all the time and literally 1/2 of the overnight charges I put it through it gets to either 80% or 100%. What I've noticed is that even when it says 80%, it still performed as if it was fully charged.
I rooted my device a few days after I got it and I honestly didn't notice the issue until after I rooted my device. So it may be different for you.
I'm not rooted. Have you tried something like: http://www.appbrain.com/app/battery-calibration/com.nema.batterycalibration or manual calibration deleting the battery stat file? I'll gladly root if it solves this problem.

To show how squirrely battery charging is, I monitored with Battery Monitor Widget and looks like this, one charge overnight without unplugging:
(each grid line is 1 hour, little over 1 day shown, screen was NOT on during charging)

I dunno, maybe its not quite problem, just curious. When I had Palm, there when I unplug my phone, it immediately turn 99, which is normal I guess, because from mathematic view, hope you will understand.
But on my SGS2 I have 100 for some time. I am using Battery widget for monitoring battery, so I see, when I charge there was 4188 mV (calibration used here), I unploged, now it is 4150mV, and still 100%. Weird.
So is there something with it?? Do you have the same with it guys??
Thanks for replies.....

Nothing is wrong. Android uses deep sleep feature which allows it to drain very little energy while locked and throttling while idle, so you'll stay at 100% for a while. That's perfectly normal.
Also if battery loses some of it's physical capacity over time due to charging cycles - the new, lower capacity value will still be reported as 100% when fully charged, it'll just go down faster.
wow is this thread ridiculous.
back in the day, people were satisfied with 3 or 4 battery bars, just to be generally informed whether they would have to charge the device next week or the week after and these days people are obsessed with their battery life (partly due to it being generally poor). i can understand the many people who are falsely claiming the android os bug, most of which are just unable to understand percentages, other people want to show off their battery life by running the phone in airplane mode and never installing any apps, just to show off "who has the longest", while robbing their phone entirely of its purpose...
and here we are, debating about fractions of % of the battery level which mean absolutely nothing.
i guess it makes sense, that 100% stays for longer than a second, because until 99.5 percent, it would round up. or maybe it counts from 100.0 to 99.1 and only when the .0 digit is triggered, the number goes down by one, effectively most of the time showing you 1% more than you have, but honestly, WHO CARES?
Hey guys, I know these threads aren't exactly welcome, but this was kind of weird.
I was carrying out my papers, listening to my Spotify playlist. After about three hours, I had 34% battery charge left. About ten minutes later, 11%. Then my phone died, because the charge was gone and it didn't get past the boot logo.
I arrived home about 10 to 15 minutes ago and tried to boot my phone, it booted and had 24% charge - how does that work?
Here's a screenshot

I'm running MIUI polimorph JB 4.1.x.
Any explanations would be nice.

Internal resistance of the battery increased due to high temperature, voltage dropped to shut off threshold. After the phone was allowed to cool the resistance dropped and voltage returned to the actual 24% level remaining.
It sounds like your battery could do with replacing.

Sounds reasonable, but I don't think so. I was doing my paper round at ~1 degrees C and my phone was in my front pocket of my jacket, so it was pretty cold. (Now thinking of that, maybe I should have written that in the OP, as well.)
But I think you're right with the battery exchange. Ever since I got my replacement S III I've been having better and yet again worse battery charge-durations. It lasted longer, but took from ~10PM charging through my XBox 'till 2PM when I go out and stuff...
But still, thanks
My S3 (2nd phone) battery lasted ages when I first got it but now a few weeks later it seems the battery just doesn't last as long as it did when brand new. I'm simply going to replace the battery with a new 1 every 3 months

There are several possible causes to your issue
- When batteries are cold, their capacity drops so when you get home it warms up and has some charge left
- Your battery's electronics had an incorrect counter. Do a full load/unload cycle and it should calibrate correctly

I don't think it would be a faulty counter. The phone was so dead it didn't reach the boot logo.
I'd say option one is most likely.

Recent update also adds "soft change" which charging a bit slower, lower voltage and about 10% less (after restarted the phone it "adds" 10% re-calibrate\stretching ) after that the battery recognized as 2450 instead of 2700ma
it should save battery total life in expanse for shorter run time per charge
anyone using it?
( i usually using phone for 3-5 years b4 buying new one, so it's important to me of its working especially when the battery is not removable)

sorry for my pretty bad english
When i first heard about this, i didn't think much of it
Tried it last night and after a whole days usage, it still had 58% (Usually I would be on <10%)
I think it does help, just takes longer to charge

I think that was just a weird coincidence. It is my understanding this is meant to prolong the lifetime of the battery (from 1-2 years to 4-5 years).
And this means that with this "battery optimization" option enabled, when it reaches 0% with ("battery optimization" enabled) it actually still has 30% left, or some thing like that. It just lies to you that it's at 0% and shuts the phone down. And maybe also not put as much charge in the battery ie. instead of charging to the previous 100% it charges to only (what would have been)80% (but it still shows as 100%, because of a software change).
This results in putting less strain on the battery (by never actually fully charging or discharging), hence giving it a longer "lifetime" from the usual 2 years to 4 or 5 years. There is a study here about this.
In your case you were probably lucky that no app started misbehaving, or you used it less than usual. My battery level at the end of the day varies widely from day to day.
Where can I find this option? I can't find it in settings.

Never mind I found it. In About -> Status
If you don't need battery life much, just leave it on. They put it there for a reason.
But if you're the type that upgrades phones every year and you just want more battery life (day-to-day usage). Turn it off.
I turned it off.
is it affecting battery life or last longer? i mean the energy not the health of real batteries on phone
sorry i'm not good at english
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!
