There are tons of threads about this already. I had the same problem and I had to play with the notifications. I turned off Facebook, Twitter, Flickr, etc. so they only refresh when I open those apps. Now, my battery lasts for 10+ hours. Good luck!

Some of these my not apply to your phone and some may be for rooted phones only, but here's my list.



1. (Doesn’t apply to all phones) Go to settings/wireless & networks/mobile networks/Enable always-on data. Uncheck always on data. Your phone will still receive email, text, & phone calls as before as well as internet usage but your battery will last a lot longer.

2. Emails: I don't know what email app you use, but try this. It saves battery power and in some cases emails arrive quicker. This scheme will have you using only the Gmail app on the phone for all email accounts whether they are pop3 accounts or Gmail. Go to the Google Gmail inbox on your computer and log into the Gmail account. On the top right of the screen is an option called Settings. In there is an option to have the Gmail program poll your regular, non-Gmail accounts. Provide the email address and the password. The Google Gmail program will then poll your other accounts on a frequency from 1-5 minutes and push the email immediately to your phone. The polling frequency is determined by each account's activity - more emails = faster polling. It will always be no less frequent than every five minutes. This saves battery power because on the android OS pop3 accounts are polled at a frequency of 1-30 minutes and that really eats battery. Because the phone goes and checks those accounts for mail whether there is mail there or not.

3. If you are using Live Wall Papers, stop!

4. Use wifi any time it is available. It uses a lot less power than 3G and it is much faster.

5. If there are widgets that automatically update (facebook, weather, etc.) change their update frequency in their settings menu. Set them to 30mins or 1 hour.

6. Oh, almost forgot, get the extended battery from Verizon.

7. Turn off the GPS unless you are actually using it. There are some background apps that can burn a lot of power via a live gps.

8. The Power Control Widget is a good tool for easily turning on and off some of these features (gps, wifi, screen brightness, etc.).

9. From the home screen do the following: menu/settings/About Phone/Battery Use. This graph will show the 10 biggest power users on the phone. It should always be Screen as the top user and the android os, android system, phone standby and phone idle should be the other top users. If there is an app listed you should determine if it’s an app you actually use a lot or do you have a rogue app that needs to be uninstalled.

10. Get Screebl. It will turn your phone off anytime you are not actively using it.

11. If you have either a task killer or an anti-virus app installed, you should uninstall.

12. Go to data>system>and delete batterystats.bin after you've charged your phone to 100%

Really? I should delete the task killer? I thought that saved battery life... and the AntiVirus too?

Task killers cause more headaches than anything. They drain battery, make apps go rogue, and are just plain unnecessary (there's a sticky on this). Anti-virus is also unnecessary since there really aren't any viruses out for android, except two of them (articles on this as well), if you want it for safety then go ahead and keep it, but to me it's just a waste of battery (if you have the live protection on).

As for battery life, yes it's horrid, but here are my tips.

1. Any auto-update features, turn'em off (unless you really need them)
2. Turn off auto-brightness (i use power widget to choose brightness or go into the setting itself)
3. Try JuiceDefender, it's free and helps alot with battery life and other features.
4. Don't check your phone every 5 minutes. I used to do this with my Droid 1 alot, but with the Incredible I've learned I don't need to check it every 5 minutes because it is a heavy toll on the battery.
5. Make sure you go to settings-->applications-->running services, and stop any apps you don't use from running.

Make sure GPS, bluetooth, and all that other good stuff is off and your Incredible should last well throughout the day.

You mean to say that we should uninstall the task killer and rather kill the services and running applications without it..?what are the important services that we should never kill?

Here's a good explanation I found a while back:

Task Killers Per Lifehacker:

Android Task Killers Explained: What They Do and Why You Shouldn't Use Them
How Android Manages Processes

In Android, processes and Applications are two different things. An app can stay "running" in the background without any processes eating up your phone's resources. Android keeps the app in its memory so it launches more quickly and returns to its prior state. When your phone runs out of memory, Android will automatically start killing tasks on its own, starting with ones that you haven't used in awhile.
The problem is that Android uses RAM differently than, say, Windows. On Android, having your RAM nearly full is a good thing. It means that when you relaunch an app you've previously opened, the app launches quickly and returns to its previous state. So while Android actually uses RAM efficiently, most users see that their RAM is full and assume that's what's slowing down their phone. In reality, your CPU—which is only used by apps that are actually active—is almost always the bottleneck.

Why Task Killers Are (Usually) Bad News


Apps like Advanced Task Killer, the most popular task killer in the Market, act on the incorrect assumption that freeing up memory on an Android device is a good thing. When launched, it presents you with a list of "running" apps and the option to kill as many as you want. You can also hit the Menu button to access a more detailed "Services" view, that lists exactly which parts of each application are "running", how much memory they take up, and how much free memory is available on your phone. This set-up implies that the goal of killing these apps is to free up memory. Nowhere on the list does it mention the number of CPU cycles each app is consuming, only the memory you'll free by killing it. As we've learned, full memory is not a bad thing—we want to watch out for the CPU, the resource that actually slows down your phone and drains your battery life.
Thus, killing all but the essential apps (or telling Android to kill apps more aggressively with the "autokill" feature) is generally unnecessary. Furthermore, it's actually possible that this will worsen your phone's performance and battery life. Whether you're manually killing apps all the time or telling the task killer to aggressively remove apps from your memory, you're actually using CPU cycles when you otherwise wouldn't—killing apps that aren't doing anything in the first place.
In fact, some of the processes related to those apps will actually start right back up, further draining your CPU. If they don't, killing those processes can cause other sorts of problems—alarms don't go off, you don't receive text messages, or other related apps may force close without warning. All in all, you're usually better off letting your phone work as intended—especially if you're more of a casual user. In these instances, a task killer causes more problems than it solves.
What You Should Do Instead

That said, not all apps are created equal. Many of you have used task killers in the past and actually found that after freeing up memory, your phone works a bit better. It's more likely that this is because you've killed a bad app—one that was poorly coded, and (for example) keeps trying to connect to the internet even when it shouldn't. Any performance increase you experience is more likely because you killed the right app, not because you freed up loads of memory (or, in many cases, it's just placebo). Instead of killing all those apps, find out which ones are actually causing the problems. If you really know what you're doing, you may benefit from using a task killer to stop the one or two inefficient-but-loved apps on your phone.
Note, however, that this is still a contested notion. A lot of developers (including ROM builder extraordinaire, Cyanogen) will not even look at your bug reports if you're using a task killer. In this humble blogger's opinion, your best bet is to stay away from regular task killer usage entirely. If you absolutely have to have that one battery-killing app on your phone, though, kill away—just be aware that when you experience a recurring Android bug later on, the task killer may be at fault. Of course, you can just stop using it to determine whether that is or isn't the case.

Based on usage. I would think a "normal" user should be able to get "from early morning to bed time" on one charge. May have to have the extended battery if usage is above "normal". I think almost all smart phones these days, for most people, end up making the day and having to be charged each night. Just one man's opinion and YMMV!!! :)

I would think an easy fix would be to switch to one of the sms apps in the market. The apps that replace native apps are almost always better. Try Handcent. Good luck.

This post is an excellent example of someone with zero first hand experience repeating misinformation. It is required to have an education in how computer actually work to understand why task killers are GOOD and why they speed up your phone. When android reallocates memory to other apps this process takes time and CPU cycles which is why your phone slows down when you have system memory full (which you will if you dont kill the apps running). I always find it funny when people state what you have stated. They think the reallocation of memory happens like "magic" instantly. They think this because they have no idea how android or linux in general actually operates. As I said before, the memory reallocation process does NOT happen instantly like "magic". It takes time and CPU cycles and this time is what you feel as the phone slowing down when system memory is full of apps. All this has been confirmed via acatlog and is undeniable. BayouFlyFisher, please refrain from posting "made up" misinformation about task killer apps when you have zero first hand knowledge of the situation. As I stated before your misinformation has been disproven via acatlogs quite a while ago.
