More on Li-On batteries in mobile devices

Posted by onlydarksets on October 28, 2007

Following up on this post, more from mrailing:

The readout on the battery life remaining is an estimate of the actual reading. You will notice this after a long call it might jump way down and then 20 minutes later it will come back up 10-20%. The CPU is estimating the life left with the current load on the system.

The best thing to do is get a feel for the system, fully charging every night for a week and see about how many hours you get on a charge, use this as your baseline, especially over the first couple of weeks owning the device (since you will be playing with it more than during this time than you will weeks later when it’s all setup the way you like). For me, I can easily go from morning to night on a charge, with the occasional topoff in the car or at my desk. I got in the habit of doing this with my i730, any time I am around a charger, plug it in. Li-Ion batteries are not affected by any memory issues, and it’s actually ok to top them off. A quick 20-30 minute charge can bump the life substantially since Li-Ion batteries, depending on their size, typically charge to 80% in the first 30-60 minutes, and then trickle charge to 100% (which is why many of you are seeing 80%…). It takes almost as much power to charge a li-ion battery to 80% from 20% as it does to 100% from 80%. But when you use your battery it drains slower in the first 20-40% then it does in the last 60%. This is just how li-ion batteries drain and work. They provide equal power over a greater period of time compared to Ni-MH batteries, but work a little different.

So, use it, top it off, don’t run it flat, and you will have good battery life. If you search the i730 forum for “battery life” and use my username in the username box, you can find lots of explanations of best usage of a li-ion battery and a little more detailed explanation…

Maximizing battery charge in mobile devices

Posted by onlydarksets on October 23, 2007

Just charge the battery to full charge. It takes a few cycles of Li-ion batteries to reach their full potential. Typically to get the best battery life with Li-ion batteries you want to drain to at least 50% for a few cycles, and then charge to full. You never want to drain fully (although they contain circuitry that prevents a FULL drain) Li-Ion batteries, since they once they get to a certain point they have a difficult time charging again.

Also with these batteries, you want to top off the charge whenever you can. These batteries like this. Although they still need to be exercised occasionally, but draining to 30-50% and charged up, keeping a constant charge on them is something that is GOOD for them.
