Battery Life on the Sidekick3

So you’re having bad battery life on your brand new Sidekick 3. Before you open your mouth and start complaining, give this a try:

  • Charge the battery fully
  • Allow the battery to drain completely (play some mp3s, do a lot of web browsing, keep the backlight on for 5 minutes, etc. to make it drain quickly)
  • Enjoy the depressing low battery alarm
  • Charge the battery fully to 100%
  • Rinse and Repeat…
  • We tried this and noticed a significant increase in battery life right away. We got to 12+ hours with heavy internet usage all day long. One thing we did notice but aren’t sure of the validity: When indoors and with a bad signal, it seems the battery drains more quickly as it searches for a tower.

    On a similar note, yes you will see the battery having weird percentages sometimes after charging. Ours likes to show more than 400%. Either reboot the device (1+@+0 at the same time) or plug/unplug a charger and if should go back to normal.

    Finally, hang tight, since the battery is now removable, there are companies out there working on extended life batteries that will keep you going for much longer. Be prepared to drop a few $$s for them though.

      you can send pictures to them and instead of them sending it to your phone they could jsut type ur email in the “phone number” area…its really not that difficult…only if you whine, and bitch and make it difficult…i do it all the time..i send pictures using the different server script at the end like or something…and then when they send to me just enter the T-mobile email…whats so hard?

      i am having a problem with charging my battery, when i first got my sk3 on the 29th, i turned it on and drained it that evening, while noticing when taking pictures was bad because there was static, i called CC, no help. i felt like i was talking to someone that didn’t know what they were talking and suggested for to try to take a picture in the sunlight the next day, whatever. i have been using the sk since the color sk. anyway, then when i got to work the next day, i started charging it at 8:30 in the morning while it was off and it was still charging at 5. i called CC and told them what was up, the fool i was talking to was trying to tell me all new phones need to charged for 10 hrs, which is a bunch of bull. well i should be getting my replacement on the 12, after talking to numerous CC reps, but now i started charging my sk3 since 7 this morning, while it is off, and i turned it on at 2, checked what the meter said in the menu and it said 97 percent full. it is now 3:30 and it is still animating indicating that it is still charging. this is bad if the new on does the same thing, i never had to charge any of my sk’s for longer than 5 hrs.

      Ok I hope people are still reading this thread because I have some info that you may or may not know about regarding the battery.

      This message is particularly for timebomb and don7juan84real :

      I had the same problem as you two. But I read that you should charge the SK3 WHILE IT IS ON. In fact, from what I hear, MOST battery problems have been resolved after people started to charge their device while it is ON. I’m not sure why you have to do this but it has something to do with electrical currents and such. Anyway, it worked for me and lots of others. So drain your batteries people, plug it in while your SK3 is ON, leave it alone or 4 hours or so and it should be good as new. Which it should be considering the fact that it IS new lol Good luck!

    9. timebomb Says:

      Thanks for the response GreekPharoah. I called T-Mobile and after talking with 4 different people, someone suggested this to me. It has been on and charging for 4 hours, but still not saying it’s done even though when I unplug it it tells me it’s at 100%. I’m going to drain it completely tomorrow and try again, hoping for the best.

      i always charge my battery when it is on.

      this morning i checked the battery and it was at 91% after charging all night long.

      CC is such a pain in the neck! they want me to send my phone back before i get another one.


      did everyone else have to get a new one that way?

      that is so wierd how greekpharoah suggested that to charge when it is on. out of the 4 or 5 times i have charged mine, one time i did leave it on the second time i charged it and it was fine, after 4 and a half hours or so, it was full. when i get the new one, i will do the same and charge it while it is on. did it say that in the manual? i am one to read the manual, but not this time, i will have to look over the whole manual and see what else i need to know. as far as yesterday when i started to charge it at 7, it was still charging at 530 when i was leaving work. i hope charging it while it is on helps, other wise i’ll send it back and i guess i’ll just have to say goodbye to hiptop, even though i really don’t want to, but it makes no sense to be passionate when it causes headache. as far as tmobile not sending one until you send your old one back, apparently it is a new policy on sidekick and blackberry, however if you complain enough you can get a supervisor to approve sending the new one then sending the old one back, i have done that.

      mine is fine
      it lasts about 11 hrs on a 11pm-6am charge

      The the guy suggesting draining and charging, go read up on lithium ion batteries.
      They DO NOT have a “memory” like old school rechargables. In fact, draining a Lithium Ion battery will shorten its life and in some cases kill the battery. For this reason most devices shut down with some charge. (although the battery meter is empty. It’s like how you can drive about 30 miles after the gas light comes on in a car)
      This is demonstrated in that, in most cases, you can turn your phone right back on after it forces itself off and the device will shut itself down correctly versus just cutting off like you pulled the battery. Keeping the charge at about half makes the usable life (or lenght of time that the battery will take a charge when recharged) almost triple compared to draining as fully as possable then charging.
