Once in a while, when your significant other yells at you, you might use your phone a bit less. Rate this thread to express how the Xiaomi Mi Max 2's battery performs under light use. A higher rating indicates that the device goes a long time when you're using the phone sparingly: no gaming or video/audio streaming, light web browsing, some calling and texts, etc.
Then, drop a comment if you have anything to add!
Used the phone sparingly, but did have some gaming in between, hence the few big dips in the timeline.
Charged back to 100% in about 2hrs without using a QC enabled charger.
9 hours of SOT, 3 days since last charge and 22% left! Normal usage, auto brightness, no power saving tricks.
Battery life is amazing.
Left it on for five days with Wifi, Data and everything switched on, without using it. Battery was still over half full.
I only once got it down to the battery warning level in a single day, and that was through exceptionally heavy usage. Most day's it's at least 60 percent after a few hours of screen time, and listening to music pretty much constantly.

Hi,
I've been noticing that my Hero has been gulping battery down VERY fast.
In general, the battery lasts 7-8 hrs, which is not acceptable (I'm out for 12+ hrs).
My usage is not heavy. Wifi, Bluetooth and GPS are rarely, if ever, on.
I do read some news and surf the web a little but only for 2-3 of those 7-8 hrs.
Is my battery life normal?
I've been reading people achieving 12+ hours with their stock battery...
2 or 3 hours websurfing is very heavy on the battery, much more so than phone calls. One of the biggest drains is the screen and you having it on for 2 - 3 hours is going to drain the battery I guess
Seems very poor, much poorer than my iDevice that I use more frequently.
Today, after flashing the 2.1 ROM, it has gotten worse.
Battery's down to 40% in 6 hours, and Battery Usage shows 50% phone idle, 50% cell standby.
I've not even touched the phone since unplugging it 6 hours ago ;S
Is it possible I've a defective battery?
If your battery is down to 40% after 6 hours of it being idle (no screen but switched on) then either you have some power hungry app(s) running in the background or the battery is defective.
At the moment my battery is showing 40%. It was last charged about 40 hours ago, and I have had it switched on the whole time with some light use, picking up emails in the background and occassionally switching the screen on.
I ran task killer and sync was off.
One thing I didn't do was charge it for 10-13 hours straight on first charge; I just unplugged it when the led turned green in ~4 hours (impatient...).
Could this have affected battery life?
Nope - when the LED is green it is fully charged. No minimum charge times suggested in the manual.

That is amazing battery life, I never get more than 24 hours with similar use... what ROM and radio are you using Peter? Also, where are you and what network are you on?
I am in UK on Orange, and have standard Orange ROM and Radio - not the latest one but the one they had before 2.73.61.5.
I have read lots of complaints about battery life, but I think mine is fine for a smartphone. I am a relatively light user of a phone - don't do lots of surfing or watching videos. A few phone calls, very few texts, checking emails and listening to some music is all I normally do with it. The other thing I do use it for is I always have the sat nav on while I am driving, but in that case it is plugged into my Brodit mount and charging from the car.
This latest spell may have been helped because I have not been out over those 40 hours - spent the weekend at home, which means that the Hero has been logged into wifi rather than trying to use mobile data. And not used it to make calls or texts or used the music player.
I notice keep Internet connection active take a lot of battery. Go to settings and turn it off and try to see whether the problem exist. It'll will take you a few seconds to re-establish the connecting whenever you need it... not so unbearable considering it'll save a lot of battery.
Same, I notice the mobile chip is using abnormal amounts of battery.
In the morning I watched a 40 minute episode of drama.
Battery dove from 100% to 65%.
To preserve battery life, I turned Airplane mode on.
When I was done with the episode, there was still 55% battery left!
I'm pretty shocked at the battery drain.
I'm using one of the new 2.1 ROMs. They're known for having a bit of a battery-hunger. I solved it by installing the app Ultimatejuice from Market. it's a pay app, but it's worth it. It's also another app called juicedefender (free, less options) that I used before I bought the Ultimate. It also worked good! Now my battery lasts the whole day without any problem
Hey guys the more i use my note daily it seems I'm hating battery life already. I basically have all features turned off and the screen brightness at its lowest. my battery usage is saying about 2 hours and 45 mins of screen on time till completely dead over an 8 hour period. What's the usual you guys are seeing on this. For only actually using the phone for about 3 hours with no games or special notifications or refreshes. Wifi is off I'm under clocked to 1.1. The battery is atrocious. I know its not made for battery life but being it has a larger battery then any cell and a little smaller then the razr Maxx i expect a little more. Makes me think there is a problem.

A couple of things come to mind:
1) Have you checked CPU spy to make sure you're going into deep sleep? (are you aware of the bug with disconnecting the charger while the phone is sleeping?)
2) Are you in an area with LTE and WiFi most of the day? I know it's opposite of what we're used to, but we've learned that the WiFi radio actually uses far less power than the LTE radio. Just something to think about.
Just some thoughts.
When mine goes into deep sleep I loose 1% per hour (wifi off, data on). I agree you need to get CPU Spy to be sure yours is going to sleep. When the charge wakelock problem occurs I'll loose 3% per hour - that adds up to 1/3 of the total battery during a 12 hour day. The work-around so far is to make sure you wake the phone AND unlock it before unplugging it. Most people only seem to have a problem with non-stock chargers and charging from USB ports.
The single biggest battery user is the screen. I highly recommend using Screen Filter and setting up a Widget set to 75% to use indoors and during cloudy days (then another Widget set to 30% for dark rooms - and turn it completely off for full sun). LED screens use less energy the darker they are, which is why this helps. I go into it in detail here: http://forum.xda-developers.com/showthread.php?t=1544757
Then there is the overnight charging problem (not related to the issue in the first paragraph). Once the phone hits 100% it only trickle charges for a little while. You know when the trickle charge has ended because that's when the "unplug me" nag comes up if your phone is on, or the screen comes back on for a few seconds showing a full battery icon if the phone is off. Once this happens it stops charging - so if your battery was almost full the night before you could hit this stage by 12 or 1 am, then it will start to run down again so the next morning it will appear to discharge fairly rapidly. If your phone is heavily discharged the night before you might not hit this point until 3-4 am (or later if you are using a non-stock charger or USB port), so the battery really will be nearly full the next morning and it won't appear to discharge as fast. The only way to get around the problem is to boot in the morning and then leave it plugged in for 15-30 minutes, or if it is already on, unplug and then re-plug it. Either way it will re-start the charging process and top off properly. The stock charging algorithm is just too conservative IMO. It should cycle the trickle charge mode on and off for up to 8 hours to ensure overnight charges really give you a full battery the next day, and not a battery that is only 96% full. Right now it allows the battery to drain back to 95% before automatically starting the charge process over. So ironically the less you use your phone the day before the less battery you'll have the next day if you don't top it off.
I'm going into deep sleep immediately if i leave my phone off the charger over night prolly 6-8 hours I'll only lose maybe 3 percent at most with wifi on. My standby time is awesome its my on screen time that's the problem. I don't have lte available where i live yet. My phone is always at 98 percent max after charging. I did check out a screen filter before but do i seriously need for my 750 dollar phone to look like sh*t to make it through a day? I jumped from a 4s to here where i got at least 20 standby and 6 plus hours screen time before charging with medium auto brightness full notifications enabled. Granted it is a smaller screen but its also smaller battery with what i would think is more draining data features. I thought led screens were supposed to draw a lot less power? My basic reason for the post is wanting to know what everyone else was concluding from average use of screen time before needing a charge. 3 hours of screen time is like two movies and my phone is dead. What's the point of a big screen cell if i always need to charge it after light use every few hours. Its basically a tv at that point which is always plugged in.

Which is why I recommended Screen Filter. It doesn't make your screen look like crap, applying a light filter (like the 75% I recommended) just dims it down a little. It works along with the stock auto-brightness feature, too. Using this I get 4 hours of screen time with 15-16 hours total run time. Most people report 3-3 1/2 hours of screen time w/o using Screen Filter. You won't get 6 hours - count the number of pixels on your old phone compared to this one.
With no tweaks other than lowering the brightness I'm averaging right at 4hrs of screen time.

i get about 4-3 hours of screen time with my overall screen time ranging from 10-16 hours depending on what else im am doing.
i also have profiles set up to keep my cpu in check while in call or screen off. i keep my phone on 100% brightness ALL the time as well. so if i did choose to dim it i could probably squeeze more life out of it.
Ya I'm at 27 percent right now 13 hours on battery about 2 hours of screen time with screen filter at 64 percent the phone brightness all the way dim. I can't see 4 hours if i tried. I dunno what the hell is wrong. What roms are you guys running? Any refreshes on face book tango scramble with friends etc. i lost about 5 percent over night with everything on. I'm using go launcher and handcent sms mostly occasional Facebook checks and fancy weather widget i use system tuner on demand 192-1.5. with screen off on 192-718 max and call settings. I drop like a percent like every 2 mins it seems when the screen is on. Also I'm on unofficial alpha 2

Hello,
I've been wondering if it's possible to recalibrate how the system reads the remaining battery charge. I'm using Rage 2.8 kernel for FXP and battery life is very good (over 30h with moderate HSDPA youtube streaming, browsing etc.), but what bugs me is that it goes from 100% to 80% extremely fast, then it slows down as it reaches 0%, it can hang on 1% for an hour before it finally shuts down.
I'd like it to be somewhat linear (even if the real physical battery discharge cycle is not linear), is it possible?
Cheers!

Depends how you and other apps really use the phone.
I've done idle testing with screen off and no apps, the drain is simply faster at the beginning after charging and later slows down to the point where streaming youtube "eats" less power than idling at 99%. I'm not saying it really does that (because it's impossible), it's just that (I guess) the physical battery discharge curve is like this, but that doesn't really help me at all with estimating how much time I have left.
I may be wrong, but I've tested this twice now (going from 100% to 0%) and it's always faster in the beginning completely regardless of what I'm doing with the phone.
I dont want to **** on the cake but if you care about battery-life you should not use a CM-rom. I used CM-7.2 for 6 months and now switched to a stock-based rom (Spartan). The result is twice the battery-life. CM's battery consumption is horrible especially when the phone is idle. I used to lose 20% during 8h of airplane mode. Now i lose 1-2% without airplane-mode.
Actually, the battery life is just fine for me. I agree, pure CM 7.2.0 drains the battery like there's no tomorrow, but Rage kernel alleviates that by a lot.
The reason I don't use official rom mods is that I like CM a lot, and while battery life could get some more love from the devs it's certainly not that bad, especially with Rage kernel. 30h+ with normal usage, internet, browsing, youtube etc. isn't that bad.
My problem is not that the battery is drained fast, but that the percentage display goes down unevenly regardless of usage. Let's say we compare idle to idle, no airplane mode, no background apps. When the percentage is at 99% it goes down about 5% in an hour (I didn't measure it with a timer, but it's a good estimate), while when the percentage is at 20% it goes down about 1-2% in an hour.
Here s an also weird graph!
Stock Rom .62 rooted.
Check the vertical drops!

Ok, after deleting battery logs after fully charging the phone (although I don't know whether it was this or something else, maybe it just needed three charges) I got a linear discharge curve. Also, now it turns off at 2%.
BTW battery life on CM 7.2.0 - this time (with LAGLESS governor) it got the phone to 59 hours, which I think is really good enough. Rage kernel FTW. Of course, with LAGLESS and stock rom it'd probably reach over 70. Still, I don't need that much, and CM is great.
-- edit --
After another change (switching to 2G when data transmission isn't needed) the phone eats 0.6% battery per hour. Now I really don't need stock.
It's amazing how much we actually use our phones in a given day, especially when we watch "videos"! Rate this thread to express how many hours of screen-on time you can get on the HTC U11 Life before depleting the battery.
Then, drop a comment if you have anything to add!
So I know this is probably atypical, but as I've been on my phone a lot today, I thought I'd check my SoT when I hit 15% battery. I'm coming from an old Nexus 5, so I'm probably more easily impressed, but my phone has been on battery for ~12 hours with an estimated 2 hours of life left and a whopping ~6 hours 24 minutes of SoT. This is a heavy usage day for me, and if this is my battery expectation on a heavy day, I will never have a SoT issue with this phone.

Me too come from Nexus 5 and can only agree. I was a little concerned about the smallish battery, but it looks like it will be enough for my usage.
Right now i have:
last full charge 14h 3m
screen usage since full charge 4h 17m
and i have 53% battery left
I'm not really satisfied with battery life of my less than two months old Realme GT 12/256 GB.
What is your average screen on time on this phone?
Mine would be in the 3.5-5 hours range in a day and a half, maybe more if I watch a movie or something.
I'm not playing games and only have Viber, WhatsApp, Facebook... usual stuff.
I didn't see any tanglible difference between "auto" and 60 Hz screen mode regarding battery life.
Also, what percentage of battery drain do you see overnight?
I'm on latest firmware, tried every possible battery saving combination, but always have at least 3% battery drain overnight (usually around 4% in 7-8 hours) and that with radio and all apps off and various battery saving settings applied (global and per app).
I'm starting to believe it's "normal" for this phone and its SD 888 chipset.
Thanks.
Same
I have very similar results as you. Battery life is just ok.
Current battery life:
from 93% to 28% in 1d 19h, SOT: 3h 15min.
Before this I had Poco F3 for a month or so and I don't recall exactly, but it was something like a 1%, 2% max. drain overnight with pretty much the same usage pattern.
Also I have Lenovo tablet with far weaker MTK CPU but not much bigger battery (5000 mAh and 10.3'' screen) and that one almost doesn't use battery in standby mode (beats all phones I had).
I'm currently disabling various apps and testing and I'll post here if I find out something useful.
Optimized standby - Ultra standby makes exactly no difference in my current setup so I turned it off completely.
Quick device connect is also turned off and not in use, as far as I can tell.
