[Nexus 5 Q&A, Help & Troubleshooting] Primokorn:
Tips for better Battery Life

These tips are going to be a collection of all I know, as well as contributions from you guys over time...that I will add in. Unless of course I completely disagree. Lol. (I.E. Task killers, Juice Defender type apps....etc) ;)

First thing is first, since it seems to cause the most problems......and so many can't live without it. Lol. Location Services.

Location Services

Location Services is so very poorly implemented in Android, its almost absurd. The service itself isn't so much to blame for battery issues, but its weakness to getting exploited by other apps. Social apps being the worst offenders. Its also very hard to pin down the offending apps. Yes, many have no issue with location services. They're the lucky ones. Sooooo many do lose a tonne of battery life to it tho, usually by excessive wakes caused by apps accessing it.

So, my first piece of advice. TURN IT OFF! Use your toggles. On when needed, off when done. It doesn't take long, its a couple clicks. Guaranteed you see FAR greater battery life because of it.

If you must use it....just must.....know that Batter Saver is NOT the most battery friendly setting. Device only is. (GPS only). Don't know why, talk to Google for an explanation. Signal strength for data I bet. And of course, high accuracy will drop your battery the quickest.

Location history reporting. Battery killer.

Android Device Manager. Found in Google settings app. "Remotely locate this device", battery killer. Neat feature....but will cost you battery time. And the other option, "remote lock and erase"....surely takes its share of the battery pie also.

So, device only is your best bet, but not so great indoors. Probably won't find the satellites. But it will be far better on your Juice. One way to use location on and help stop apps from abusing it, is Grrenifying the apps that use it, or using app ops or its equivalent to change app permissions and disallow them location permission.

K, I bashed on location enough. But it is the number one item in most issues I see.

Signal Strength

A weak signal is about the quickest drain a phone can have. If your signal is very weak and spending time out of service and scanning for a signal.....your battery can literally drop like a rock. The worst part, Gsam and similar apps don't really indicate the signal, radio or anything else is draining your battery. I'm not sure why these apps can't report the loss from signal, but I guess its just not possible.

Very hard to "fix" this issue.

- Your first option, get on WiFi. Its not really the text and phone part of the radio draining you, its data. If your signal is poor or non existent and apps are trying to sync over data.....the phone is working overtime trying to transfer the data. Getting on WiFi will fix this. Even with poor signal strength on the radio.

- Next option, toggle off data in poor coverage. No, your social apps and what not won't work. But you'll still get texts and calls. When you have a signal. This will dramatically slow the battery drain.

- Last option. Airplane mode. Yes, you will be completely cut off from the world. But your battery will barely drop.....assuming you have no issues and your standby drain is good.

Of course, combine poor signal with location services on high accuracy or battery savings....with data on....and you will be charging by lunch time or have a dead phone.

Roms and Kernels

I won't say much about this. There's those who will agree with me and those that always ask "what's the best ROM/kernel for battery life?". MOST experienced users will agree....ROM/kernel combos will make minor differences occasionally. Its all about setup and usage.....and signal strength.

I always say.....I could run any ROM or kernel (and I almost have) and will still get 24 hours plus with 6 hours SoT consistently, with my lean setup and low CPU demand usage. Guaranteed. Now, if you want me to prove it.....I wanna be paid for my time. And I'm not cheap. ;)

Kernel tweaking, such as under volting/clocking, may gain you small battery life returns at best. And also possible lag and instability. Lots will disagree with me here. But thoroughly test it out yourself and see. ��

But to each their own I always say. Personally, I can't remember the last time I changed any kernel settings from whatever one I'm running. I just don't see the point. Fun and experimentation perhaps.....but big battery savings.....not gonna happen.

Last kernel thing......double tap to wake, even with the timeouts it has now.....lots of battery drain.

Greenify

I use it. Some don't. I use it on anything I know is going to run when it feels like and possibly steal my battery juice or cause any issues. One app I've always greenified is Maps. If it comes with the ROM, I convert it to a user app with titanium backup and then Greenify it. Games, any I ever have, greenified. I don't need or want to know my farm is ready to harvest. Lol. I'll find out when I open the game. ;)

Use at your discretion. I wouldn't Greenify anything I use often, like dolphin or Tapatalk.....it'll just use more juice constantly loading them into memory. Social also won't sync if greenified. And be very careful greenifying system apps. That can cause you issues for sure.

Greenify tip from [MENTION=5666997]Lethargy[/MENTION]:

The paid version of Greenify let's you choose an option for Greenified apps called GSM push, when used with Xposed and the Greenify module activated. It allows you to still receive push notifications from hibernated apps. So you can Greenify those social apps that like to spam location services and burn data when your not even using them....and they will be awoken when you get a push notification. Will help with the drain from these apps better than doing nothing with them for sure! ;). A happy middle between always running and totally hibernated.

Screen Brightness

I think we all know a bright screen will cost you lots of juice. Out in the sun, there's not much we can do about it. I go back and forth sometimes. If I'm outside all day, I just usually put on auto brightness. But, nothing will help you save juice more than setting it manually. Someone not long ago mentioned an app called "Display Brightness ". Its free, and puts a very customizable slider anywhere around the edge of your screen that you want it. It gives you a quick access slider on your screen and its always there no matter what app you're in. You can change its size, location, color, transparency... Etc. Great little app.

Anyway.....if you keep the screen as dim as is comfortable for you, you'll get big gains in battery time.

I'm not convinced about LUX and its equivalents.... But many swear by them. Definitely something to look at too.

Tasker

I know little of tasker, I've never really got into it much. I did pay for it....and can't say when I last used it. Lol

You can do amazing things with it....to automate much of the things I've mentioned. A great tool for sure!!!

I've just never minded using toggles myself. :)

A few Quick Ones

- The more vibrating your phone does, the more juice it will drink.

- Games. We all know they kill the battery fast. Nuff said. :). (Keep the screen dim)

- Social apps and other things that sync....the more you have, the more your battery time decreases. Especially picture heavy ones, like Facebook. It takes data transfer and CPU time to load all those images. Also, some wake your device a crazy amount of times to keep you up to date with your friends. :) (See Post Number 3 for help on controlling these and much more!!!!)

- Task killers. Guaranteed they waste more battery than they claim they'll save. Opening apps over and over is far worse on the battery than them sitting in memory idle. (In most cases. Greenify the exceptions). Android RAM is meant to be used. Too much free RAM is not helping, its wasted RAM.

- Juice Defender and other battery saver apps. Most will agree, some may not....but again, waste more juice than they save. For a moderate to heavy user, setup juice defender and look at your times held awake later. It can easily get over 2000 wakes per day.

Now...for a very light user.....very light....like you barely touch your phone all day....then Juice Defender may actually help you. But only the very light user.

Summary

Not all of these things are for everyone....but with each piece of advice you take, you'll save a little more juice.

Is my phone no longer a smartphone? Many have said that. Lol. Well guess what....in a few clicks, my phones intelligence can skyrocket. I just don't need things running 24/7 when I don't need them....or never use them.

So, here is a quick checklist of what I personally do after I install any ROM. And again, my battery life is as good as most I've seen. I'm just sharing this, not suggesting everyone do it. And also, all of our needs, usage and apps we use vary.....so there's no way to all have the exact same setup. Or the same battery times!!

After every install:

- I go into accounts/Google. Unchecked the things I don't want to sync. Usually I only have gmail, calendar and contacts checked.

- I turn location to device only, location history reporting is usually off for me by default, so I don't need to remember when I actually use it, then I turn it off completely.

- I go into Google settings app. In android device manager, they are both unchecked. Google Now is off. In ads, I check opt out of customizable ads. Location is already off.

- Sound settings. I uncheck all the options at bottom. No click sound, no vibrate on touch...etc. ( my keyboard makes no sound or vibration either). My phone only vibrates if I set it to vibrate. Otherwise it never vibrates on calls or notifications.

- I change a few cosmetics. (No battery impact here)

- I download titanium backup and restore my apps. Only user apps, and only data on the ones I don't want to setup again.

- change my wallpaper black. Not sure on an N5 if it helps battery life whatsoever.....its just my visual preference. :)

- Go into titanium backup and freeze, NOT uninstall...everything I never use.

- reboot.

- I Greenify all the apps I usually Greenify.

- Nova gets data restored, so not much to usually setup there. Its just how I had it.

- Restore the only widget I use. An agenda widget.

- Start LMT, Gsam, Display Brightness app and light flow...on some ROMs. The ones that have customizable notification LEDs by default, i don't use light flow. All of these get restored with data, so no setting up preferences required. Kii keyboard as well. And I disable the Nav keys.

Well, that's my setup routine. Again, to each their own. Just sharing my way. ��

That's all I have for now. Formatting (and spell and grammer check) will be tweaked to be easier to read in days to come. So no need to comment on my many mistakes. Lol. Plus additions I think are helpful from the community will be added. Along with credit, unless you don't want it. :)

Just whipped this up quick to help those that want it. I'll make it prettier soon. Promise!!

Good luck! ��
