Hey! So I bought a new battery for my Moto G4 Play! Original and new. Since last full charge it lasted 24 + 18 hours = 42 hours! My question: can I make the battery last more? I've read briefly about underclocking and undervolting the CPU and that some custom ROMs are more efficient.
I decided to analyze what is consuming the battery, results below. I'll make some rough translations too.
Consider my battery has 2800 mAh
The screen (Tela) takes 27%, that won't change, it is consuming around 18 mAh/hour
If we combine smartphone/cellular waiting (Celular em espera, ambiguous translation), Android System (Sistema Android), idle phone (Telefone ocioso) and Android operating system (Sistema operacional Android) we have 27% + 9% + 4% + 2% = 42% of the battery consumed by those, that's like 28 mAh/hour
The rest consumes 100% - 27% + 42% = 31% -> 20 mAh/hour
If we can halve the consumption from the system, we get like 14 mAh/hour, so now we can assume the battery would last (18 + 20 + 14)x = 52x = 2800 -> 53-54 hours of battery, that's more than 2 days and an actual improvement of 23%.

Any pointers of what to pursue? Do you think I could realistically halve battery consumption by the system? What should I try? Otherwise I'll just leave it as is, I'm happy with my current juice!
Turns out that cellular connectivity simply eats my battery. If I manage correctly airplane mode and activate and deactivate WiFi or the SIM card as needed, it is reported that my battery can last 5-8 days! Crazy huh!?

Here are my results for today (so far)...
Battery percentage remaining - 41%
13h 33m 9s since unplugged
voice calls- 1h 11m 27s. - 62%
display - 1h 13m 35s. - 22%
cell standby - 13h 33m 2s. - 8%
phone idle - 12h 21m 51s - 5%
Bluetooth - 10h 12m 11s. - 3%
android OS - 19m 5s. - 2% -
I thought the battery life was questionable at first but now I realize that it was because was 'playing' with it CONSTANTLY. I guess the "new" has worn off and I used it more like a Phone today and my battery use seems good compared to previous smart phones I have owned.
What's eating your battery?
at 17h, 25m im at 61% with
display at 42%
Phone standby and idle at 22% each.
Ive been home sick so my phone hasn't been used much.
display - 68%
cell standby - 13%
phone idle - 6%
android system - 4%
android os - 4%
those are my top 5, I took my phone of the charger at 7 am, it is now 7:40 pm, and the phone is screaming at me telling me to plug it in.
display-43%
voice calls-32%
cell standby-11%
phone idle-7%
android system-3%
mario live wallpaper-2% wow
android os-2%
android core apps-2%
Live wallpapers are cool and all but they really aren't practical.
^ 2% makes them not "practical?"
looks like "display" is a trending topic...lol
Here's mine (52% battery remaining)

solved my problem i think
I've had problems with my 3g connection being quite choppy and only getting 1 or 2 bars since I got the phone. It must have been using a lot of juice in it's struggle to maintain 3g. I changed the setting to 2g networks only a week ago and Ive had a great connection to the Edge network. My battery now has 60% or more at 5p with a good amount of use. Before I would have to be charging my phone at 5p. Im looking into the issue some more.
ok 27 hours since unplugged.... and 71% BATTERY LIFE? mind you display was used 1hr 58 mins too and brightness is set to auto not lowest setting or anything!
WIFI was on for a total of 17 of those 27 hours tho
WIFI POLICY SET TO NEVER SLEEP
GPS OFF
USE WIRELESS NETWORKS ON
Baked snack rom 1.3 set cpu is clocked at 1.2ghz out of a possible 1.3ghz
2 google accounts 1 syncing emails the other syncing contacts & calendar
facebook is syncing every 24 hours
Drm not present in this baked snack rom 1.3
The proof is in the pudding people WIFI is a HUGE!!!!HUGE!!!! battery saver
we are talking an easy 300% better battery over 3g! at 27 hours I would be at about 25% or less not 71%

nice but try it with pure 3g ?
Very nice indeed but our phone uses the old 3g radio instead of rev0 so our battery will doe quicker which id why wifi is a huge difference.

recall! lol
In other words, you are saying the battery doesn't die quickly if you don't use it as a phone, and don't turn it on?
You can still make phone calls and send/receive text when 3g is off.
Doing this will save battery life noticeably.I was turning it off, before the last update.
Battery life was horrible then. Installed a data/3g off and on widget to do this easy.
After the last update, battery life was awesome and I did not have to do this anymore.But I still have the widget, in case I get into a situation that I cannot charge the phone and I will use this method to conserve power
I never tried the wifi thingy though
This is mixed use of 3g and wifi. Beat that...

Been about 2 hours since unplugged and been on 3G, played maybe 5 minutes of Angry Birds, 2 emails, 2 2 minute phone calls, few texts and browsing the android market for about 10 minutes. I'm now at 84%
Compared to the rest of you guys out there, what would you call this? Eh, so-so, decent, great, outstanding? So far anyway.
Keep in mind my RADIO and PRL have not been changed from factory since the phone has been switched over to Boost Mobile and I don't wanna lose settings since I had to pay to do so originally.

Check your Display on time, divide that by 2, add number of hours off a charger. That's how many percent of battery you should have used since unplugging (with average use between, calls, web browsing, texts, game playing etc.)
In other words, using display/cpu (with autobrightness and apps which don't consume ridiculous amount of cpu time, like 3d games) consumes about 0.5% per minute. The standby usage with 3g on will consume <1% per hour.
Anything larger than those figures, and you have a problem.
I got it. Does the Display on reset itself once a charger has been plugged in? I originally took my phone off charge around 1:10 this afternoon, plugged it in for a very brief moment (2 minutes) to put a .apk on my SDcard. I noticed my "time since off charger" reset, so does the same apply for the Display?
So it does. I'll do a full charge over night and report back.
does your 4g connection work? or you get a sprint web site?
Lately my battery stats behaves a bit strange like this

what could i do? :s I have tried different roms and kernels, now i'm on purity rom + m-kernel. Maybe a battery problem? I calibrated it with an app but unluckily it hasn't worked... Thanks in advance

Battery calibration does not affect the actual amount of current drawn by the device - any device.
At best all it can do is make a slightly improved prediction about how much charge remains.
But on the N7 I don't believe it even does that. In any event, it will not change in the slightest little bit *when* your battery runs out of charge, nor will it perform some kind of voodoo magic where your tablet will use less current, either.
in the N7, there is a "fuel gauge" chip (TI BQ2745 ?) that monitors battery voltage and current in & out of the battery, from which it produces a "% charge" value directly from the firmware embedded in that chip ( and read by the kernel across an I^2C bus). There is no OS-level software which alters this.
The upward movement in apparent charge level is a little bit unusual, but it is not unusual for rechargeable batteries to show a "voltage rebound" when they have been operating with high current draw and then operated in a very low current mode (e.g. tablet sleeping). Perhaps that TI chip just isn't all that great at dealing with that "rebound" behavior.
The rest of your graph shows the battery draining about 42% of the time ( = 0.42*7.75 = 3.26 hrs).
During that time your battery graph says you lost about 40% of your charge.
The way I do math that works out to a full-scale "100% discharge time" of 3.26/0.40 = 8.1 hours.
That doesn't seem to be much to be worrying about.
Hello,
I've experienced a sudden change in battery performance.
What used to take around 50% of battery now takes around 85%.
It happened recently, around the same time I started working at a new workplace. The reception is horrible there, maybe that's the issue. However during the weekends, it is around the same.
I was on 4.4.2 stock when it happened and since then I've flashed it again once. I've also tried a couple of different radios (and enabled LTE) and I've always had franco kernel.
Brightness was always on Auto (which I shall turn off to experiment battery life) and wifi is selected to be off when the phone is off.
I have still a few more experiments to do, but I'm considering using warranty services. What do you guys think? It's clearly not as bad as some of the other battery issues I've seen on this forum, but it's quite the change for me. I bought this phone in July 2013.
Here is an example battery usage graph. Charging finished around 1 AM and left it unplugged over night. In the morning (~7 hours) the percentage was at 75%. (5% / hr) Throughout the day, I have used it for text messaging only and by 6 pm, it's at around 13%.
Thanks for taking the time to read my long post.

You can check what drains battery with BetterBatteryStats. Google it and you'll find.
Thanks for replying.
I have tried that before an OS reset although I couldn't make much out of it. One main thing I noticed was a certain kernel wakelock which, after I googled, was responsible for LTE connectivity. Although this makes sense, I had good battery life even with the LTE chip being used (& auto brightness / wifi always on) prior to this battery incident. By good battery life, I mean 50-60% used by the end of the day
