when i got this diamond phone last week the battery performance
was bad serving me with less then a day worth of power where i
had to buy a second battery.
now that i have been off from work for a few days (3 days) i finaly
had the chance to cain this phone properly eg. flipping wifi on/off
through out the day listening to shoutcast, lenghty periods trying
to setup LAN, listening music while out on the road and checking
emails, looking on the net, yapping on the phone and sending txt messages.
to my supprise the battery seem to be holding up pretty good. now it
appears to be holding out till the end of the day where before i had to
carry two batteries now i think i can get away with carrying just one.
here are my stupid questions
1, does htc batteries get better performance after multiple charges?
2, did i have a semi faulty battery and now a miracle has happend?
3, am i just dreaming that the more i use the longer the battery stays on?
today i charged the bat. at 9am (ish) and now its 3,45pm. i still have 3 bars
remaining im supprised as from before a few days ago this was not the case.
im using the daimond with no mods and standard battery.

suprised!

hiya mate,
I am going through the same thing. First day I got the phone and battery was awful about 4 hours it lasted me! very shocked. but it is holding out.
I did charge the phone initially for about 12 hours as specified but don't know if that helps.
what i tend to find with new mobiles is that you have to charge fully and then DISCHARGE FULLY the phone numerous amount of times to get it to perform to the best of its abilities. I don't think its anything to do with HTC batteries, just the fact that new batteries have never been used and need to learn!

you are half right. this battery life is improving if you keep charging it but it is not advised to fully discharge them.
the fully charged-fully discharged method was for the old batteries with "memory".
somewhere in this forum, in the trinity forum somebody experimented the two ways of charging-discharging the battery. the conclusion was that it is better to charge the battery anytime, any occasion u have.
Indeed, the battery's performances (and this is applicable to all common batteries) will increase by time until it reaches its max capabilities.
To gain performance, the battery has to discharge and charge very frequently, or better, continuously. I don't really know how the Diamond manages it (meaning if the battery is full, will the device still get power from the battery if it is plugged on, or will it drain power from the cable. It could also drain from battery if it is fully charged and charge it in the same time, or it could simply always take it from the cable and charge the battery in less time)
The reverse is also true, meaning if you don't discharge/charge your battery frequently enough, its performances will decrease by time.
Also, if your battery discharges and charges all the time, it's lifetime will be longer than a battery that is only used once in a week.
I don't know if I made it clear, lol.
By the way, don't think that if you keep charging your battery you will end up with weeks of battery, there is a limit and it is 850mAh on the stock battery, if I remember correctly.
thanks for the tips some say discharging is good and some say dont.
all i know its 8:35pm and i have only used 1 bar from around 4:30
which now leave me with 2 bars. im jumping for joy because normally
by 6pm ish the battery would have already died.
with all the hammering today i cant believe it only took 2 bars in nearly
12 hours and thats with no extra charge from the psu and only 5 usb
connections to the pc to sync and add files totaling 2 - 5 minutes
on each connection.
now i can officially say this phone is "DA BOMB"
time to sell the e90 and e65
The thing that kills the battery on this phone above everything else is the GPS - knocks it out in 90minutes or less. If you were having fun (even for a few minutes) with it in your first few days, this might explain it...
GPS?

yeha that would explain it but the thing is I haven't even installed TomTom or any other GPS related app!!! weird. but i've had it for about 4 days now and battery does seem to improve slightly on a daily basis.
Lately, I noticed that when charging my tilt with the charger, it takes forever to get to 65% and then in almost no time, jumps to 100%. Is that normal? Does something need to be done? Do I need a new battery? If so, what's recommended?
Separately, when using WIFI, it uses over 400 mA -- that's outrageous.. Any way of improving that, while still being able to stream audio (ie power saving settings may be an issue)?
What's a good battery meter to help debug things?
Thanks
I have the exact same deal going on with my battery charge. Started happening not too long ago. With the stock ROM and with hyperdragon III ROM, I always see the jump.
I'm not sure what the problem is but I figured it was a false charge in that the battery's capacity has really lowered from the original 1300mAh. Also, thus why your batter drains much faster than it does (so does mine). If anything, it's probably just a normal battery problem which could probably be solved if you got a new battery. I haven't tried (yet). The battery life went from 3 day's of casual use with some data connecting here and there, to 1 day and if im lucky, a day and a half.
Hope this helps out a little. And if anyone has the real solution, do tell. Thanks.
Regards,
K
I had the same problems. Took forever to charge. Battery life was horrible. Could only make a 3 minute phone call on a 100% charge before the phone would shut off. Ended up being the OEM battery was done. Lasted about 1 year on heavy use. Bout a battery/cradle charger from Amazon that came with an extra battery. Also bought another 1600mah battery. Both of them work great. No more charging problems.

I too think it's a faulty battery (which may still be covered under warranty). It's always a good idea with the TyTN II to have at least one spare battery for long trips etc (I have the original and 2 spares as well as a cradle which recharges spare batteries). The O/P should try another battery to confirm that works normally and if so and the original battery is still under warranty, contact HTC/The supplier to see what can be done. IF they need the phone (and I've never tried claiming on a battery under warranty), make sure it is fully reverted to 'as from the factory' status using all official ROM/Radio/SPL before sending it in.
Edit: The o/p could also try cleaning the battery terminals (using a cotton bud soaked in contact cleaner) to make sure high electrical resistance has got nothing to do with it.
I received my new lg g watch r yesterday and so far as much as I'd like to use it it won't last long at all off the charger. Got it at 30% and it up out of the box. Whilst trying to charge the watch it was losing charge whilst on the cradle.
It was at 90 percent this morning and within less than 30 minutes it was at 32 percent.
I've factory reset the watch and factory reset the nexus 5 it's paired to and both running stock up to date software but still horrific battery drain. It's draining faster then the charger can charge it?
Any help would be greatly appreciated as I don't want to return this shock peace of kit
Sounds like you need a replacement - if both devices are totally stock, and it can't even provide enough power to charge, there might be an electrical short within the watch.
Yeah thats not right, yesterday i took off charge at 7am 100% screen on all day, lots of fiddling, it died at 1.20 am. so 18 hours use. Sounds like you have a duff battery.
I used to have bad battery life. I would get about 12 hours with my device. When I got it, I played heavily with it, and ended up enabling bluetooth debugging. I didn't think much of it, but later when trying to solve my battery issues, I disabled bluetooth debugging and now I get about 2.5-3 days of battery life! Before discovering this, I tried switching to digital watch faces, no weather, steps, etc on watch faces, but that barely affected battery life. The bluetooth debugging though, if I enable that again, the watch dies in 12 hours again. It's a huge difference for me, not sure how bad it is for others, but be aware that this can impact battery life quite dramatically.
Im not sure if im correct but i guess you have let it at least 4-6 hours for the 1st charge (by this you increase battery life ) so my opinion is to call lg and exchange it because the lg gives 1,5 days of battery life
Hello, I hope all of you are well and I can get a reply or suggestion from you guys for this.
I have a new P20Pro. Bought it on the end of October.
The battery life is absolutely great with almost two full days of usage.
The issue I got is this.
When I am using my phone and it comes on the last 10% of battery it staets droping by 2-3% immediately. So it will go from 10 to 7 and then 4 and then 2 and immediately shut down.
The whole thing would happen to 3-4 mins in total.
When it gets to 2-3% it says it will shut down in 30secs and never goes to the last 1% or 0%. The other thing that bothers me, connected with what I said before, is that when I connect it to the charger when it turns off completetly, usually starts charging from 2-3%, almost never starting from 0. Today for example turned down when it was 4% and started charging from 12%>
I have tried almost everything, recalibrating the battery, doing the charging cycle correctly, wiping the cache and factory resetting it and also chenging the settings but nothing seems to be working.
Any ideas please ?
What you describe is usually a battery problem on older phones and a new battery remedies that. Mine us also in a bit of hurry ti switch off below 15% so I make sure to keep my juice always relatively high. I might take it for replacement of battery in a few months to have a new one after 500-600 cycles [emoji4]

Mine starts shutting down at 6% I think! It's caught me out a few times, thinking I had at least another 20 minutes.
I can't complain about the battery life though so no big deal really. Conversely when I unplug from a full night's charge it can stay at 100% for ages whilst using it.
I'm guessing either calibration is a bit off or EMUI is really going the extra mile to protect your battery from being damaged by draining too low.
almost 2 full days usage?
man I barely get one day, the battery is being drained quite quick
I just switched from OnePlus 5T to P20 Pro, and the battery life of the first is way ahead (and recharges much faster)
maybe there's a problem with my p20pro?

Hi!
Follow the below steps.
Phone manager>Do optimise>tap on battery icon>Optimise battery usage. And dont let any apps to run in background. Using auto start manager you can control the apps which are running in the background.
and please post the battery usage details and check which app is consuming more battery & kill the apps which are consuming more battery
Hopefully it would help.

Hi Thanks for your help
I will definitely do it and will keep yous updated
Meanwhile, let me bring something else: My phone doesn't supercharge. Even when I use the original cable + charger (and plugged straight into the wall) it doesn't fast charge. Doesn't display that it is being supercharged or something and it will take about 3 hours to finish charging.
This is a brand new phone which I got last week.
I used to have an OnePlus 5T which recharges pretty quick but this P20 Pro, although it is a beautiful phone, charges like my old Moto X.
Anything else I need to setup in order to enable supercharge?

Download Ampere from the app store and see what the charging rate is.
When almost empty I get a rate of 4200mA ish.
The more it charges the lower the charging rate.

When I use the original chargers from Huawei, it won't get past 1800mA
Then I went to visit a friend who got a Mate 20 Lite, he has a fast charger and I tested his in my p20pro and it went to ~2300mA (and then it displays in my phone "fast charge"). However, if we use on his phone, it will go more than 3500mA
The supercharger won't come by default in the box? I'm asking because when I got at home I checked the output of my recharger and it shows 4.5-5v -> 2A, it seems it isn't the fast/super charger
Hi there! What you have described with the battery percentage going to 3% and then immediately to 0% is an issue on ALL Huawei phones. I had previously owned a P10 LITE, a Honor 7C, Huawei P20 PRO and Mate 20 Pro. They all do this. I suspect it has something to do with the reserved battery percentage . It shuts down quickly so that it can keep 2 % and not drain completly. I do not know the benefit of this but all phones do it, however Huawei's software implementation is so poor that it actually displays wrong percentages. It has nothing to do with the battery being old. They do it straight out of the box and ufortunately do not know of any solution to this.
Just an update:
I had a chat with the store which sent me the phone and then they sent me the correct charger with supercharge.
Now it works well and on Ampere it shows 4.5A

Goto Phone Manager touch power saving->Optimize.Phone Manager will rapidly identify apps or features that are rapidly drainning the battery.Touch the Optimize button net to each or feartures to disable it and start saving power.You can touch Recover to re-enable the app or feature.When you remove an app from the protected apps list,your phone will close the app automatically when you turn off the screen to save batterry.
H, since I updated from miui 10 to miui 11 and even now that I have miui 12 I have noticed that the battery doesn't last as long as before. I state that since I purchased the phone (July 2019) I have always charged the battery in the best way trying to never go below 20% and trying not to go beyond 80% so I don't think a battery can lose more than 30% of its real capacity in less than a year of life. Starting to investigate I found that the battery does not charge at its real capacity i.e. 3300 mAh but at around 2200/2300 mAh. To verify all this I have carried out several tests and the easiest way to verify it is to look at the battery characteristics through the AIDA64 app (screenshot below). From these tests it seems that the device limits the real battery capacity by not allowing it to be charged to its maximum capacity. A reply to what I wrote can be found by looking at some system files that are located in /sys/class/power_supply/battery. In particular, looking at the file called charge_full (screenshot below) you can see how the value of the file is much lower than the real battery capacity. I hope someone more competent than I can understand how to solve this hateful problem and I also invite you to check the value to try to better understand the cause of this problem.
I'm using miuimix 12.0.2 stable and the capacity is not 3300, either.

And sorry i don't know how to post a picture, mine is 2943.
I know that batteries won't be forever and are always decreasing during the year but I think Xiaomi do a good job. I have some devices from 4 years ago and they reduced their batteries just a little. In the case of Mi 9 I have it since March 2019 and my battery still being the same. I charge it from 10-25% to 100% just some times I charge it until 80-90%, maybe every month I let it to 0% I wait for a while and charge it again to 100%.

From the photo you posted it doesn't seem that your battery is fully charged .. we have done other research and we have discovered that most likely Xiaomi has inserted in the kernel a sort of programmed obsolescence on the battery.
Can you disclose some of the research you done on the kernel it seems interesting. I have checked with Aida64 my battery before and it never charges to 3300 even if you leave the phone plugged in the value will keep increasing but once you plug it out it drops...still getting about 5 hrs sot so not bad...I wonder if you change that value in the full charger screen you posted what will happen?
"From these tests it seems that the device limits the real battery capacity by not allowing it to be charged to its maximum capacity. "
Actually it's better for battery life longterm to keep the device in the middle - never 0, never 100
I've certainly lost no battery life in the year + I've had the Mi 9
You are doing a good job of using the phone in the 20 to 80% range. But do you charge it at the lowest possible temperature? Temperature is a battery's worst enemy. Wireless charging is a joke. It's a glued heater in the battery.
I for instance, almost all the times charge it in front a mini fan. With this I can charge it 5ºC below normal temp charge.
And like @cezikos said, use quickcharge only on emergencies. Use at max a 1.5Amps charger. Quick charge is a marketing thing. The chemistry of the batteries are almost the same in this 10 years.
Mi mi9 have one year and the battery is 100%.
The important thing that you should precise is a type of charger that you are using. Do you use Quick Charge? If Yes, then battery capacity will be dramatically degrated. I use 5V 0.5-1.5A charger, it depends how fast I need to charge the Phone.
The next thing is a battery temperature, not Only while charging the Phone but also when you are using it. I`m using CPU Monitor and it's overlay to see the battery temp, you can also configure alerts when battery is starting to overheat.
Heavy Gaming decreases the life of the battery, there are a lot of variables that you have to cobsider, not only "programmed obsolescence"
I had the same problem. Hopefully the battery could make 3 hours of screen, the strange thing was that suddenly it began to last very little, and I was with that problem for a couple of weeks, so I decided to calibrate the battery hoping to have some results and now the battery lasted again approximately 7 hours of screen. Try to make the battery run out from 100% to 0%. The system will not let you start because it calculates that it has no battery, so what I did was leave it in recovery mode and with the screen always active, until it turns off completely, then with a 5V 1A charger. With the phone turned off, charge it until it reaches 100%. I did it three times and the battery was back to the way it was before. You could try to do the same and I hope you can solve that problem.
Sorry for bad English
I tested, I put the phone to play videos until it turned off. In 1% I cleared battery stats.
Then plugged the charger and entered the TWRP and unplugged. Put the backlight to maximum, and the phone stayed on more than an hour!
Then I plugged the charger 1.5A and let it charge to max.
It worked, now the phone has a steady discharge, not discharge 100% to 80 in an hour.
I will do this procedure from time to time. not the best for the battery, but is needed in mi9...
It's an absurd that this problem exists in 2020, my galaxy S2 don't have such harsh problems with something so simple and basic like battery management!
Battery on my Mi9 (mildly used in one year) lost 500 mAh.
Confirmed, with this trick, in doing it ONE time, I have the phone running well again, more than 8h screen on.
0.5 discharge in sleep.

Thanks! I just don't know how to clean the battery status...
You will need root.
Then are several apps that can do it. Like l speed or adiutor.
And now again confirming, in one month the phone is completely lost regarding battery again, just 3h SOT from 80 to 20. There's some pretty **** up code regarding battery in xiaomi android.
I have no problems at all using it since release.
newest xiaomi eu.
I also have problems with battery drain...
Hello guys, just want to share with you a little trick that just helped me get better SoT. First of all, I just want to mention that I'm on the newest xiaomi.eu rom (20.8.13) and that AccuBattery is showing that my battery is at 2500mAh estimated capacity. (That might be different in reality, because it's only after one charging, so don't believe it that much). Lately I noticed a significant drain while the phone was idle (screen turned off). It was draining like 1-2% every hour and I could barely get over 5h SoT. So I investigated a little bit, and found a solution on reddit. The thing was that I had many apps on autostart. If you want to check them and turn it off then open Settings > type 'autostart' in the search bar > open it > 3 dots > show system apps > turn off every unnecessary app that you think don't need that option. I turned off every app, except: Gmail, GPay, Google Photos, Clock, Calendar, Bank app, Weather app and the app called 'safety system addon' - it might be called different because I'm not on english language on my phone. I left them on just in case to have notifications/synchronization, though i don't know if it's necessary. After that there was almost 0% idle drain over the day. Now I'm on 5h4m SoT and still have 25% of battery left. The result might be even better, cause I did this trick just today while my phone was on 90-85%.
Give it guys a try, hope it will improve your daily experience with Mi 9.
P.S. Let me know guys If I could turn off the before mentioned apps and still get notifications and sync from them.
Mine reports 2800mah, debloated with Szaki tool all autostart apps disabled also did factory reset after miui12 update.
Really sad how bad miui12 has turned for me. Im having way worse battery life compared to miui11 the idle is mostly the same its just the battery doesn't last as it used to last with miui11.

I can confirm this. AIDA64 said my battery was at 2550mah capacity when fully charged. I followed this procedure and now after being fully charged, it says 3125 mah, which is much better.
I'm curious about the screen on time now. Me happy. Thanks!
