HTC EVO 4G :: Solar Charger - External Battery Backup
May 26, 2010
I am planning on getting the EVO come June 4th to replace my HD2, and I am wondering if there are any solar chargers available on the market for this unit. Since I will be having a case on the unit, I dont want to be having to open the back cover all the time to replace the battery whenever its dead. maybe a good external battery backup might do the job.

Looking forward to warmer weather in the NE US and thinking about nice long bike rides. I am psyched to have such a cool little GPS/computer/map system and plan to take the Droid on long rides. Some will be 3+ hours and I don't want to worry about running out of juice. Researching it looks like I have a few options and wanted to know what you all think. Mostly I think the droid will just sit in my Jersey pocket with screen off but tracking GPS. Occasionally I will check maps.
1- buy a spare battery - weight- not much, 1300 mAh - Downside, sometime during the ride I will need to swap batteries and restart GPS apps that I might be running. This would be really annoying so I think this is out as an option.
2- battery extender like Satechi iCel 4400 mAh Battery Extender. Pricey but would certainly give me enough ride time & gets excellent reviews
3 - Solio H1000 Universal Hybrid Charger Not as much power as the battery extender but I really like the idea of charging while I am out riding, although it seems to charge pretty slowly and needs direct sunlight. Even without serious sun it would probably provide enough of a charge for all but the longest rides. Gets "ok" reviews

Big selling feature for the Moment over the iPhone is swapable batteries. I'd like to keep the phone with me at all times, and just swap in batteries. But I can not find an EXTERNAL battery charger. Google search only turned up a "universal" charger where the contacts are manipulated to match up with the battery. Not a good option. Anyone have a source for an external battery charger which I can use to charge spare batteries without using the phone?

Amazon.com: Genuine Motorola Droid P323 Battery Charger System: Electronics Amazon.com: Motorola BP6X A855 Droid OEM 1300mah Standard Battery: Cell Phones & Service Anyone use these 2 items from Amazon? I'd like to get a second battery and an external charger, this seems like a cheap solution while keeping OEM parts. The only thing I'm really questioning is the voltage output of the external charger to the battery. Any way to tell if it will charger correctly? If you know the answer, please provide reasoning.

Just saw this on Gizmodo, it's a solBAT charger for any USB device... it's a 1500 mA battery that pumps 5V through a USB hookup. It's not exactly a perfect solution to anything (especially since it seems like it would be most useful in a car, which is when you'd be able to plug into the cigarette lighter anyway), but still: you can essentially boost your battery using only the sun, and it's only $30... pretty cool!
Thought I'd post it here for anybody with environmentalist inclinations who's having battery problems... or if you're like me, and you're planning some extended hiking/camping trips for the summer, and were trying to figure out how you were going to keep your phone alive for more than a couple of days

I'm finally ready to take this phone back and I wanted to know if it was possible that I could do a complete backup or the closest thing I can do to one from my internal SD card to my external SD card? That way if I ever decide to get an Android phone again I'll have all my apps and settings.

I was an unfortunate early owner of a Samsung Instinct (returned it lol). The interesting thing about it was that it came with a convenient battery charger/case that I think would be perfect for the Evo. Anyone know where u can find one similar to the Instincts spare battery case for the Evo? Here's a link to the Instinct one Original Samsung Instinct Battery Charger Case, ABCC778BBABSTD Free Shipping!

So this weekend was my first real world test using the GPS turn by turn for a long car ride (about an hour). I had everything all set plugged in and started the music player (not Pandora) running in the background while the GPS was displaying on the screen. I also had the bluetooth synced to the car. To my surprise, the battery started to drain. It was pretty slow but after about an hour around 5-10% of the battery drained even while plugged in. Do you think it is my after market car charger from monoprice (For only $1.46 each when QTY 50+ purchased - Motorola V8, V9 Series Car Charger for RAZR2 | Motorola It has been working great in the car for about 2 weeks with Pandora playing and bluetooth.
Anyone else experiencing battery drain while plugged in the car using GPS? I think I read someone having a similar situation but with the Verizon charger. I am also using the stock battery. If not, please let me know which car charger you are using with a link if possible. I can't continue using this one if there is one out there that will keep me charged in the car.

Just read that some mobile phone battery chargers use power, even when there no phone connected to charge up. Does this apply to the charger for the Hero? I currently use a electrical timer switch for the Hero charger, but, am I wasting my time doing that?

Why can't I find a charger for an extra battery? As fast as the battery drains on these phones, it is a pain to have to plug in the whole phone to charge.

Interesting....I start at 80% battery...insert the Dx into the official moto car dock and car charger...drive using nav for 3hrs and my battery is down to 50%. I also stream pandora simultaneously. I would expect the charger to keep up but it is a losing battle....

When I got home from work today my battery was down to 20%. I plugged the charger in then started messing around on youtube. An hour later my phone shuts off and wouldn't power back on. Red led was blinking for about five minutes then the phone powered itself back on. I checked osmonitor and it showed my battery at 0% and battery temp at 140f. Will the battery not charge if your using this phone or is my charger bad?

I've had my Desire a few weeks now and am resigned to the fact that I have to charge it regularly as I have it linked to my office Exchange server using push email. As I am on call for my job I need it on overnight as well. I always plug it into the HTC charger at bed time, but this morning I noticed something odd. When I woke up (still plugged in) the battery was showing 100%. As soon as I unplugged the charger, it dropped to 90%. I've seen a similar question on the forums but the circumstances were slightly different - anyone have any thoughts, duff battery maybe?

My phone was dying so i charged it. Plug it in, 30 mins past so i went to check on it.
So i looked at it and battery is still red. And i am wonder what the heck. Everything is plug in where it should be.
Low and behold the chord connecting at the mini usb well let's just say the casing is ripping apart and the wire is exposed. I've had this phone for 3 weeks and this happens.
Verizon better give me a new charger. Also i've notice i always get Sense UI force closed and other apps force closed but if i close and start again it works.

May seem like a dumb question but I constantly keep an eye on what apps are running to conserve battery life. It got me thinking if I stopped any running app before plugging in the charger, would it will make the battery charge any quicker??

My girlfriend and I both bought this phone from Verizon last Friday. We both let the battery run down completely before charging it up (which I was told by the Verizon rep was the "way to go"), and we have both been experiencing GOD AWFUL battery life. Strange battery behavior has included (but has not been limited to):
- Battery going from 100% to 5% after 5.5 hours straight of browsing, playing games, etc., followed by the Battery going from 100% to 5% after 5.5 hours of idle (with light texting and a few quick phone calls mixed in). Seemingly no consistency.
- Battery draining down to around 30% after about 8 hours off-charger with light to moderate use (a few web pages, a few apps downloaded, and about half a dozen texts). If this wasn't annoying enough, shortly after reaching 30%, the phone suddenly took a nosedive into the red, and warned me that I had 5% battery remaining.................

Just installed SkyRaider 2.5.2 yesterday and radio 2.15. Using Launcher Pro+ and updated the notification bar to have the circle indicator. The charge took almost five hours. (Which I see is a common thing). However, when I unplugged my phone from charging this morning (9+ Hour charge) the battery went from 100% to 93% in about five minutes. It seems like I am losing 1% every minute or so until I reach 93%. Then it kind of stays steady. CPU clock is running constantly at 600 MHz+.
