My xperia only lasts about a day with moderate internet usage, with moderate amount of necessary programs running (I ALWAYS close all apps after finishing).
Just a note, all my data connections are closed & tweaked to close after 2 mins of inactivity.
I heard that X1 batteries should last for ages.. at least 2 days to 4 days.
But I heard I need to flat out the battery, and then full charge it to 100%, followed by a soft reset. Apparently, this recalibrates the battery levels and users have reported battery life extend to 2 days to 3 days more!
So, my question is, if anyone has recalibrated their battery meters is..
1) After flatting my battery out, do I full-charge with the phone OFF or ON?
2) After I have fully charged, can I use PHM Soft Reset after windows boot-up?
Thanks.
I think you should buy another battery if you want more time.
My battery is down to about 50% on average after 8 hour work day. I have push e-mail and IM client and they always cause drain. 2-4 days would be if you didn't have consistent background services running.
As far as what you are saying about recalibrating the battery I think you are misinformed. Xperia has a Lithium-Ion or Lithium Polymer battery. Generally recharging frequently is better for it than doing a full drain. The type of full drain before recharge that you are describing was common recommended practice for Nickel Cadmium or Nickel Metal Hydride batteries. These could develop a "memory" in the battery which would dramatically reduce the amount of charge they would hold before they refused to charge.
If anyone has good evidence to the contrary I would love to be wrong, but I am pretty sure that with PUSH and IM there is no way to get a 1500mAH battery to last 3 days.
Also the radio you use and the area you are in (proximity to towers) can have a significant effect on your battery life.
charge it when it off for - + 1 Hr .
it will saty about 2 days

This is not absolutely true. It's true that Lithium battaries don't develop "memory" problems on their energy storing part, but they have a small circuit and this circuit is possible to develop the "memory" effect. This circuit is the one that decides that battery is full and cuts energy supply or informs about the percentage of the battery power remaining. This circuit for example is the reason that there is no point anymore on having the battery charged for 24 hours when you charge it for the first time.
IMHO you could try emptying the battery and charging it again when the device is off. Don't try to drain the battery completely as it could damage its power storing part.
i think i have the same problem about my X1. when i full charge my battery and after a few hours it goes 50% and sometimes my battery indicator says that i have 80% and after a soft reset the battery indicator says i have 20% weird...
I have had my Galaxy S for a bit over a week now and am pretty disappointed with the battery performance. Most days I take my battery off the charger at 7am and it reaches 15% low battery warning by 1-2pm. I do spend a fair amount of time reading XDA and listening to music. I'm currently running Stock JM1 firmware with no lagfixes.
Here's a list of my apps that I have installed:
http://www.appbrain.com/user/Lokhor/apps-on-the-samsung-galaxy-s
I am running JuiceDefender which I thought would make a big difference and does not. I have also set Tasker to change the Brightness level to 20 (below the safety threshold) when the battery reaches 50% or below, otherwise the brightness is at the minimum (30%).
I have heard that you need to condition the battery so I have been trying to do this but it doesn't seem to have had much effect. Today I used my phone only casually and it's currently at 22% after 12.5 hours. The battery use details show the following:
Display at 56% being on for 2h22m and 13s.
Cell Standby 18% Time on 9h21m, time without signal 13%
Phone Idle 7% Time on 7h33m
Android System 5% CPU usage 23m39s CPU foreground 24s
Android OS 3% CPU Usage 13m 27s
Is this normal? Is there anything I'm doing wrong?
Please help
I don't know what others are telling you about conditioning a LiIon battery but you don't have to. LiIon batteries don't suffer from what NiCad do. Some do suggest wearing the battery down to nil and then charging it up again. However, this is pretty bad for the battery and should not be done more than once every 30 cycles. With every LiIon battery I've ever owned I've either trickle charged it or charged it when it wasn't too low and they've all lasted over 3 years. I've never conditioned one.
Anyway, my advice to you is to see how long your battery lasts in standby. Mine could probably last 3 days or more if I don't bother it too much (with sync, wifi and all that good stuff). I find the worst contender for battery drain is the display. The only problem I see with your stats there is that I've played Asphalt5 for around an hour and a half which is quite heavy on juice and it only drains roughly 10%-15%. Then again you're browsing the web so maybe probably worse.
Oh, and when charging your phone, don't use the USB hooked up to a computer as it doesn't stop charging when it's full. Use the wall charger to charge.
no need to worry more

I found that charging it whenever it was convenient instead of when it was low would result in a charge that lasted ~24 hours.
I've noticed significant increase in battery life since I started waiting for the 15% charge warning, plugging it in till it was full and then unplugging it. I get 2-3 days of use this way.
I also set my email to only sync between 6 AM and 11 PM. I believe this helps a lot as well.
since we are about this topic, check this out
How to spot fake battery vs. OEM battery: http://forum.xda-developers.com/showthread.php?p=7953322
so if I'm listening to music during the day at work should I have my phone plugged into the wall charger or just let the battery run down?
Last night I took the charger off at midnight when it was full and when I woke up it had only dropped 5%. After reading my emails quickly it was at 93%.
it works fine either way

I find leaving the brightness on automatic uses up loads of battery. Setting it to lowest seems to make the phone last 24hrs+
I also found that having beautiful widgets clock/weather installed used up a lot of battery for some reason.
I don't use weather because it has to sync every so often to update it which to me is a waste...I'll just look outside. I also leave brightness on the lowest setting wherever I am as the screen is already very bright (why waste battery?).
My experiences with my SGS have taught me to be conservative with its battery. Anytime you turn the screen on, you eat power like crazy. The best bet is to just top her off whenever the need arises. Personally, I have found that I'm fine just topping her off in the car when I'm driving, so that I start my work day at high 90's, and especially once I've got my morning browsing out of the way, I don't eat a big chunk of battery at any other time.
But yes, if you find you are running low, you can happily just take a half hour to charge from a USB port to give you an extra boost. Alternatively, spare batteries and so forth do the same thing, although it can be annoying if you don't have a charger that will do the phone and a spare battery at once.
im experimenting with apndroid now to turn of 3g then i dont specifacly need it. It comes with an on/off widget. Looks promising so far. 40% at 2300 hour and then i have used wifi a bit, played angry birds and talked for about 2 hours in total.
Hello,
after using JB since it was released for our Xperia T I noticed that the battery life is way different than on ICS. I can't tell if it's longer or shorter but the percentage drop differently. The most annoying thing is that after complete charge when I start to use my phone the battery drops from 100% to 99% even in 30 seconds. The next few percents drop in very short time (f.e. in 15 or 20 minutes battery drops to 90% or 85%) and then it drops slower. But still 4+ hours with the screen on is normal for me.
Do you have this issue with percentage too?
Yes its same for me...
Yep I'm the same mate. Not sure why though.

One of the safety features implemented since Froyo (Correct me if I am wrong) is that when you leave the phone on charge after it hits 100% it no longer charges the phone, even though it reports that it is. This is to keep the battery in better health.
So, during this period the battery level can drop to around 95% so if you disconnect the phone during this time it will quickly drop the reported level.
Don't forget that the reported level is not an actual reading like a dipstick or reading the amount of liquid in a measuring jug, it is calculated quite differently and the reported level may not be accurate.
Yeah but on ICS my phone was in 100% of battery even for 10 minutes when I was still using it (9h+ when on deep sleep! I love .195 build...). Then it started to drop. I know it stops charging when it reach 100% but it still suck that after a minute the voltage drops from 4180 to 4010 and the battery drops really quick.
i own Xperia TX, and on JB totally different story happens to me!!!
when i fully charge the phone, it takes usually 2-3 hours in sleep mode, with VERY slight usage of just checking sms, to drop battery from 100% to 90%, but after that, it quickly drains, F.E when i leave the phone, in half an hour, 10% is lost between 60% to 50%!!!!
battery meter is crazy, as you said, it's not measured accurately, so don't pay attention to these numbers, just get use to time that it's USABLE
Battery percentage is just an estimate created by your system, they must have changed how this is handled. I've had some phones that stay on 100% for a long time then drop rapidly, then others have been more like yours. Its nothing to worry about

It is impossible to measure the battery capacity perfectly. The energy from battery comes with chemical reaction and depends on some variables (temperature, charging and discharging speed, etc.).
And with each reboot, you add some inacurracy, because it's measured on system/kernel level (not running = no measuring).
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!
my new pixel 7 does not charge all the way up during the night, it usually stops at 40-50%
I'm using a 5v 2A charger and high quality cable (already tried swapping them ).
Do you think it could be an hardware default ?
Power if off and charge.
If it still shows 50% charge return it.
Not acceptable, especially if the actual SOT reflects that.

Did you try turning off adaptive charging?
hi
turn off the adaptive charging
I would return it immediately before you pass the window. I wanted to return mine for fingerprint reader issues, but I waited too long and now my only option is to swap it for a refurb device which is less than ideal.
Thats a good thing. Charging the battery to 100% stresses the battery, as does completely discharging it and reduces the longevity of the battery. I have mine set by ACCA to only charge to 90% and turn off at 5%.

Bump that low to at least 20% especially if you fast charge. It's the higher current load/temperature at the first 20% that causes the stress. It's important the battery is at least 72F at charge start, preferably 82-90F to avoid Li plating which will permanently degrade the cell if it occurs.
I aim for 40-80% usage range. That said on this heavily used device I expect about a 1.5 year battery life. Replacing batteries is just part of routine maintenance, no big deal.
While I always fast charge however I do midrange power cycling, what Li's prefer; it's less stressful. I'll frequently do 20% amounts too. What's convenient for me at the time. Rarely go above 90% as it's rather pointless and disproportionally increases charging time vs usage time.
Yeah, my current setup isnt perfect, but it avoids the extreme stresses while still offering me a charge for a full day.
However, my phones have only ever seen a 5% shutdown on a few occasions so there is no need to set a hard cutoff at 20%. It rarely gets that low and if it does, its because I cant charge it.
Typically I charge it in the car on way home from work, then when I go to bed. So the cycle throughout the day still is pretty ideal.
90->40%->65%->40%->90%

If you resign yourself to changing out the battery when it's degraded (80% of its original capacity) it's not a big deal.
A battery failure is a big deal though; one I had came close to damaging the display on my N10+. That battery was degraded, lasted less then 1.5 years. I got lucky that time... not going to push my luck again especially over a cheap repair like a battery replacement.
