Hi everyone,
just came across this interesting Wiki guide. It explains how to make a cell phone battery last longer between charges, and how to prolong the overall life of the battery. To many of you, it will already be common knowledge, but there are still alot of interesting pointers mentioned.
For example, it states that lithium-ion batteries should be charged for about 5-6 hours and we should ignore the phone telling you that the battery is full... it states that this is normal but is not accurate if the battery is not initialized. It goes on to say that we should NOT fully discharge a lithium-ion battery, because unlike Ni-Cd batteries, a lithium-ion batteries life is shortened every time you fully discharge them. Instead, charge them when the battery meter shows one bar left. Lithium-ion batteries, like most rechargeable batteries have a set amount of chargers in them.
Please share your findings, opinions, and any further tests you have carried out to improve battery performance for your Desire.
Thanks.
Battery Saving Tips:
There are loads of "tweaks" you can make to imporve battery life span:
1. Lower screen brightness. Go to Settings -> Sound & display -> Brightness. Slide the brightness switch to the left to lower it or check the "Automatic brightness" box to let the phone use its sensors to adjust the screen according to the ambient light. You can also find dedicated screen brightness widgets in Android Market.
2. Turn off 3G, WiFi, GPS, and Bluetooth when you don't need them. The easiest way to manage these wireless radios is to use the Settings widget preinstalled on your phone. Tap the + button on your home screen -> Widget -> Settings. Once your chosen widgets are on any of your home screens, a simple tap turns each one on/off. You can also use "Power Control" widget found in home screen -> Widget -> Power Control. There are other widgets that do this in Android Market (e.g. SwitchPro), but these are already preinstalled and they're a nice-looking set.
3. Disable WiFi and 3G network notifications. Go to Settings -> Wireless & networks -> Wi-Fi settings. Uncheck the Network notification box so your phone isn't constantly scanning and looking for open networks to tell you about. For 3G, go to Settings -> Wireless & networks -> Mobile Networks.
4. Disable "always on" mobile data. This is one of the biggest battery savers. Go to Settings -> Wireless & networks -> Mobile networks. Tap "Enable always-on mobile data" to uncheck the box. I haven't found a negative consequence of disabling this feature, as Gmail and other apps/functions still work perfectly.
5. Turn off background data. If you're not using Google services, go to Settings -> Accounts & sync and uncheck the Background data box so that applications cannot sync, send, and receive data whenever they want to.
6. Lower the screen timeout interval. The phone's screen can be set to automatically turn off when you don't interact with it for a predetermined amount of time: 15 seconds, 30 seconds, 1 minute, 2 minutes, 10 minutes, or never. Depending on what you're doing, a too-short interval can become annoying (especially if you didn't disable your lock screen), so choose wisely.
7. Manually turn off the screen when not in use. Since the screen timeout function ensures that the phone's screen will turn off (unless you have it set to "never turn off"), it can be tempting to put the phone down when you're done using it and just let the screen turn off by itself. Instead, give the power button at the top of the phone a quick push to turn it off manually.
8. Turn off auto-sync. Go to Settings -> Accounts & sync -> Auto-sync.
9. Change auto-sync frequency (Weather, News, Stocks, Twitter, etc). If you don't want to turn off auto-sync, you can adjust how frequently data is retrieved/updated. The settings vary depending on the app (and some don't offer the setting at all), but it's generally found in the same place: Settings -> Accounts & sync. Select an account from the list and then tap "Account settings" to change the sync frequency.
10. Disable wireless network location services when not needed. Go to Settings -> Location -> Use wireless networks. Note that this (or one of the other options) needs to be enabled if you want to see and/or use your location in apps like Maps.
11. Turn off window animations. To turn it off, go to Settings -> Sound & display -> Animation -> No animations.
12. Don't use a live wallpaper. Use a static wallpaper instead.
13. Use a dark wallpaper. Some say that dark wallpapers are more energy efficient than light wallpapers. Others say it doesn't make any difference. Either way, there's no harm in using a dark wallpaper so you may as well do it.
14. Change WiFi sleep policy. This may sound counter-intuitive, but leaving WiFi on when the phone isn't being used and the screen is off is actually better than letting it sleep. When WiFi sleeps, 3G wakes up to sync, get email, and retrieve other data. 3G will eat up more battery than WiFi, so go to Settings -> Wireless & networks -> Wi-Fi Settings. Press the Menu button and tap Advanced, then Wi-Fi sleep policy. Choose "Never" from the pop-up menu.
15. Monitor your running services (or consider using a task killer). Just because Android 2.1 is supposed to an intelligent operating system that will manage your running apps for you doesn't mean it will always do things the way you want them to be done.
You can take matters into your own hands by going to Settings -> Applications -> Running services, where you can view what your phone is doing and manually stop certain activities. You can also download a third-party task killer from Android Market and kill selected apps to free up some resources and potentially save some power. Task killers are a polarizing topic in the Android community, so tread lightly when looking for recommendations or asking for help with them.
16. Choose your home screen widgets carefully. Widgets that need access to the internet to update information (e.g., Facebook, Twitter, Engadget, Slacker Radio, Weather, Stocks, News, Mail) can suck up a lot of juice if not managed well, so choose them carefully and set their sync/update frequencies to a reasonable interval.
17. Disable notification lights. This may not be practical if you're someone who really needs/wants to know when something happens on your phone when you're not looking, but for everyone else, feel free to turn off those notifications. Go to Settings -> Sound & display -> Notification flash and uncheck all the boxes.
18. Turn off phone vibration. If the ringer is on, why do you need the phone to vibrate? You're already in a loud environment that drowns out the ring; answering the call won't quiet your surroundings so you can hear what the person at the end of the line is saying.
And if your phone is set to silent, then an incoming call should be silent. Yes, the buzzing vibration may not be disruptive as your ringtone, but people still hear it.
So go to Settings -> Sound & display -> Phone vibrate and turn it off.
19. Turn off audible touch tones. In Settings -> Sound & display, uncheck Audible selection and turn off Audible touch tones.
20. Turn off haptic feedback. Once you get the hang of typing on the phone's on-screen keyboard, you can turn off the haptic feedback that was turned on by default. Go to Settings -> Language & keyboard -> Touch Input -> Text input -> Vibrate when typing.
You can disable haptics in other areas of the system by going to Settings -> Sound & display -> Haptic feedback.
I just plug mine into the USB of my computer (which is on most of the time) when I'm at home. Apart from that I use my phone how I want to. If battery life becomes unbearable I'll get a spare battery.
Not too sure about the 5h charge. It doesn't make sense. First once the battery is full, its full. It depends on how this is measured, but usually when max voltage has been reached, the 100% is shown.
The charger of the Desire is 1A, while the battery is 1.4A. If its actually charging at 1A, a -completely- empty battery is fully charged after around 1.5 hours. Even if it were charging at a lousy 0.5A, battery should be fully charged after 3 hours.
So no idea where that figure comes from (perhaps very very low amp charging on other cellphones ).
And most important tips are indeed no full discharge, and (kinda hard to do) keeping the battery cool. Most important factors on battery life.
Removing Nimbuzz upped by Battery life by about 300%, not worrying about it any more now.
I read some article said the lithium-ion battery is based on the time of your recharging. That means the the total one full recharge is under counting. Say you used your battery from 100% to 50% and recharge it to 100% for the first day. two days later your battery goes to 50% again and you rechage it to 100% again. That is the total one full recharge. each lithium-ion battery can go over 2000 full recharging(I am not so sure it is the number). so it is nothing to do with the time you charging your battery.

Looking on the market, it is an IM/Skype combo thing... I reckon his battery life improved vastly as he set it to constantly stay signed in/syncing every 15 minutes which will completely kill any battery performance...
I couldn't figure out how to disable the persistent notification for the power save feature in the stock rom, and as far as I know there isn't a way to do it through the settings menu. But if you download an app called "notifications off" and uncheck notifications for the settings app, then it goes away. Use some caution, though, I'm not sure that turning off ALL of the notifications from the settings app might not have some unexpected adverse effects.
Does anyone know how to set up a task to turn on do not disturb, or priority only, or whatever it's called? Coming from htc, you could just tell tasker to turn the volume all the way down or turn on silent mode. Can't seem to duplicate that on the g4. I'm using smart settings now, but the results are inconsistent.
i think you need secure settings (plugin, playstore) to archive this
In Tasker, there's an option for Audio > Interrupt Mode - in there you can choose Priority or All. This should do what you want.
I have Tasker setup to mute the phone just before and just after the "battery full" sound plays, as it cannot be disabled (without root).

Perfect, thanks. And I was using a task to turn off the battery full sound also, until I realized that I can just keep the volume level for "touch feedback and system" all the way down. That gets rid of the battery full sound along with some of the other ones that were bothering me.
My favorite g4 tasker workarounds are to set up a task to turn the volume all the way back up again after I plug in headphones and it automatically turns down the volume "to protect my hearing", and adding an icon in the status bar whenever it's charging because I need a visual confirmation that it's still plugged in and I can't make out that lightning bolt in the default battery icon.
Is there any way to remain stock, unrooted and have a quick toggle for the location setting (high accuracy, battery saving, device only, off)?
I keep it on battery saving generally to ensure I can make full use of Google Now but toggle location on for navigation as needed. It's clunky to have to go back in to the menu manually and change it to battery saving every time. Any suggestions?
No particularly elegant way.
I do the same as you, but have my authomation app (MacroDroid) show a notification when High Accuracy is set and a press on that notification starts a Macro that uses the Tasker plugin AutoInput to switch back to Battery Saving (MacroDroid can use some Tasker plug-ins). AutoInput allows you to automate various screen touches. So still clunky but allows you to switch back with one press.
There is a Settings Widget in stock that will get you there quicker. When you drop the widget onto your screen, it prompts for the setting shortcut type. Select Location when prompted.
If you install "Power Toggles" from the play store you can customize which quick settings buttons appear and would be able to create a toggle to get into the location settings so you could tap that and you would immediately be in the setting menu you want. This doesn't require root. Unfortunately Power Toggles doesn't seem to have the ability to cycle through those settings at all without root. Getting to that settings screen quickly is nice though.
However, If you have root access you can create a "GPS" toggle which would switch your phone between "Battery Saving" and "High Accuracy" and a long press on that toggle could pull up the location settings menu if you wanted to go to "Device Only" mode. For some reason there doesn't seem to be a way to toggle "Device Only" without going to that menu which is why I have the location menu set up as a long press on that GPS toggle. I typically leave it in "Battery Saving" and if I use maps I will toggle it to "High Accuracy".
Hi guys,
There is 10-15 mins delay or no notification at all from some third party apps until I press the power button to turn on the screen - not unlock, just turn on.
It mostly happens to Gmail and the Reolink App for my security cameras.
After I turn on the screen I can receive real time message from these two apps for a while but soon goes back to how it was before.
Things I have done but doesn't help:
1. Enabled “Stay connected when device sleeps” in battery setting.
2. Set apps to "Manage Manually" in App Launch
3. Enabled all notification for Apps.
4. Set "Don't Optimise" for Apps in Battery optimisation
I even followed the instruction below provided by @klaus27 to disable PowerGenie but it is still behaving in this way.

I really dont have any idea now can any one please help me out? Thanks in advance.
