Update: this post is getting an unreasonable amount of views, given that it’s 6 years old. When I wrote it, I did not realize the battery problem would be such an evergreen subject for years to come. But please, please, read it with a grain of salt: probably everything is outdated by now.
I shared some of my recent Android experience here, with the two leading phones, Verizon’s HTC Incredible and Sprint’s EVO now it’s time to share a trick (actually two) that makes or breaks your experience with these two mobile powerhouses. Matt Burns @ MobileCrunch loves the EVO but considers the battery a deal-breaker:
Simply put, the battery sucks. It’s a deal breaker. I’m really sorry to say that, too. In fact it hurts me because I wanted this phone so bad, but the battery life is horrible. The phone will lose a third of its battery sitting overnight with the GPS, WiFi, and 4G turned off. Even with Advanced Task Killer set to aggressive and auto killing apps every hour, the most I can get out of the phone is about ten hours.
I know – been there, done that and could not believe how bad it was. In fact with everything (Wifi, GPS, Mobile Data) off and without activity, in Sleep mode the battery died in 6 hours. So why have a Smartphone if I have to turn everything off to be able to make a few calls? I refused to accept it, searched, searched, experimented, and found the two tricks that can dramatically improve battery life. They are actually simple: start with more, and don’t lose it 🙂
Start with more juice
No, I don’t mean buying a bigger battery pack. Get more out of what you already have. Charge with Power OFF. Seriously. If you charge your phone turned on, it will reach full charge status very fast. The problem is, it’s not really full, only Android thinks so. Turn it off, and recharging will last hours longer, but it will truly be full. Since it appears to be a software glitch, we can hope an OTA update will fix it … one day.
Don’t lose your juice
Keep your Apps under control. No, Task Killer and similar tools won’t help, some programs do get restarted no matter what you do. Here’s what you need to check: After power on, keep the phone in Sleep mode for a few hours. If Uptime and Awake time are close to each other, or even 2:1 3:1 ratio, you have a problem. An application does not allow your phone to go to sleep. Keep on trimming your App list (and I don’t just mean shut down, but full uninstall) until you’ll see awake time less than 10% of uptime.
With those two tricks, your phone should last 2+ days in Sleep mode, and otherwise it will obviously depend on your actual usage.
Oh, and I am switching from the Incredible to the EVO 🙂
