Cellular Phone Forum / Providers / Sprint PCS / July 2004Sanyo 8100 - battery life
My wife and I have had these Sanyo 8100 phones since November. After the recent firmware update battery life has been about half. Is there a way to get the old firmware put back on? And why would a firmware upgrade cause battery life to decrease? We used to get 4-5 days of battery life using the phones about 10-20 minutes a day. Now we're lucky to get 2 days. The phones are powered on all the time. Bruce Richards > My wife and I have had these Sanyo 8100 phones since November. After the > recent firmware update battery life has been about half.

While you are there, have your phone tested out, by the technician. > And why would a firmware upgrade cause battery life to decrease?

Took them back to the Sprint store and they reapplied the PRL update and firmware updates and tested the phones and batteries and claim there is nothing wrong with them. So now we will wait and see if they last any longer. Bruce > > > These phones were bought November 18, 2003 so they aren't a year old > yet. [quoted text clipped - 10 lines] > > Bruce If your phones are doing Analog roaming that will seriously diminish battery life between charges. Even if the cell phone is only "Searching for Service", that uses extra juice. Workarounds: - Set phone for "SprintPCS only" (if you dont need to roam) - Turn off phone if its in a "No Signal" area. - Turn phone off over night. - Use a car charger to charge whenever in your car.

BINGO - a firmware update likely will reset the default "Network" setting to "Automatic". Change it to "SprintPCS Only" (assuming you don't roam), and battery life improves!!! > My wife and I have had these Sanyo 8100 phones since November.

If I had a firmware update, it would have been AFTER I started having short battery life. When I got the 8100 last February, I could go at least two days before having to recharge it. About two months later, I noticed it was almost dead by the end of the day...now its dead by noon. Took it to Sprint for testing, all they did was offer me a free extended life battery. I said I wanted to stay with the original battery size, but it still is dead by noon, so that rules out a bad battery. Now all of this is when I'm in Sprint network coverage and have Sprint only set in my roaming options. > We used to get 4-5 days of battery life using the phones about 10-20 minutes > a day. Now we're lucky to get 2 days. Took my six month old Sanyo (brand new off the shelf) for a SECOND test because of poor battery life. As I posted two months ago, they found nothing wrong with the phone and offered me an extended battery which I declined. When I took it in for the second test, he siad it might be the battery...I pointed out the battery was only two months old. I keep the LCS screens set to like 10 seconds and set for Sprint network only. The phone was great a few months after I got it, but now its dead by the end of the day. > I keep the LCS screens set to like 10 seconds and set for Sprint network > only. > > The phone was great a few months after I got it, but now its dead by the > end of the day. I've taken both phones back for testing and they said there was nothing wrong with them. If you can stay in the Sprint network they both have great battery life but if they have to search for a signal forget it. I found a place in my house where I can set them when not in use and keep a signal and the battery life seems to be better. I just wish I could get a better signal in my house. I read a while back Sprint was working on a small repeater for indoors. What ever became of that? Who have the last Firmware Version 1.116SP?, I want to load it to m phone by my self and a software to read/wright ESN and PRL. Thanks in advanc - turbojetj > Who have the last Firmware Version 1.116SP?, I want to load it to my > phone by my self and a software to read/wright ESN and PRL. > > Thanks in advance Well, you've got the ESN on your phone. Just flip off the battery and you can see it ... twice. As for the firmware, that has to be loaded up at a SPCS store and ONLY at a SPCS store. You can get the PRL updated there at the same time, or you can get the update OTA (over the air). Current PRL is 10024. For future reference, for your current phone and any future phone you might get, check out this site as it shows the current versions on all SPCS models. http://www.sprintpcsinfo.com/modules.php?name=Content&pa=showpage&pid=9 .
