One very nice thing about the Treo 600 (having used one for a week) is that the battery life is MUCH better. Day to day, the charge level barely moves. It's reminiscent of my old Palm III that could go for weeks without battery replacement.
In contrast, all of my 7135s can only go a few days. The behavior is strange. Sometimes after a full charge, it can go for hours and it's still at 100%. Some days like today where it's just sitting on my desk, it's already dropped to 87% in under 30 minutes.
I have two batteries and the behavior is similar for both, so either both batteries are flaky or all my 7135s have been, or that's just the way 7135s are.

Given that your screen usage is a constant the other huge battery drain is searching for a signal or holding an analog signal.
Do your signal conditions vary?

I'm in the middle of Silicon Valley, a major metropolitan area. No, the signal conditions don't vary (that I notice).
Originally posted by pauljlucas Incidentally, does anybody have really good battery life? (Like you can go for a week or more without a charge?)
No chance. Most people get 1 day with moderate to heavy usage and some get 2 days with light usage. Maybe if you have a solid digital signal, don't run anything on the palm and don't open the flip you could get a week out of it Battery life is not one of the 7135's strong points.
I'm in Silicon valley too. At home I lose signal on rare occassion. You can turn on audible alerts for loss of signal and acquisition of signal. This way you're aware of it happening.

That sounds about right for Battery usage. Quick is right, the battery usage on the 7135 is not great compared to other devices but I tolerate it because of all the other neat things I can do with it. I can get a few days out of my 7135 if my usage is lite, but rarely need to push it. I spend a fair amount of time in my car between client visits so the phone is always charging in the car kit cradle. And I too have two batteries that I swap every few days as well.
Also the other huge drain on the phone is MP3 playing. I've also noticed that some Palm games will have a heaver power consumption, probably due to the amount of sounds they generate.

Yep, battery life for the 7135 has always been aprox. one day. But when my phones were experiencing signal problems (shortly before going SRCP up), they only lasted a few hours to half a day (because it kept searching for a signal). I thought that my batteries had just met their end, but once they were placed in a non-SRCP phone, they were right back to full days.

I too have noticed this short battery life of a day (compared to a week with the old 6035). But what I have noticed (even with turning off the sound with the searching for lost signal) is that over last few weeks the battery seems to be more and more drained by days end even when I am in same area of my office (which has a poor signal). It finally got to the point yesterday that by 6 PM I got the low battery indication and finally the shut down mentioned in another post when battery is drained. I wondered what this would d to stuff in memory but as mentioned in post on battery completely draining the capacitor held charge and all was fine as soon as I put phone in charging cradle.
What was most interesting (and why I am writing this for feedback) was that by totally draining the battery I seem to have restored the battery to a full charge (although indicator always indicated a full charge after night in cradle). The battery lasted all day with no drain in the indicator with phone on all day and being in the same low signal area (my office).
So my question/observation is this: Does fully draining the battery seem to allow for some kind of full recharge that does not happen if I always charge at days end when battery is not fully drained? Does the battery suffer from the old memory problems of some batteries and need to be fully drained sometimes?
Any ideas, feedback on this would be most appreciated.
Originally posted by salsbst Does the battery drain faster when the signal is low? Or only when the signal is not found ("Searching")?
Usually when the singal is not found. In my buidling here on the U of I Campus I get one or no bars (just tower) and often it searches because of weak signal. So the drain on battery is definately as others report due to the searching. I tried saving some on the battery by turning the searching sound off but I guess the search is the main drain.
Anyway I am curious why this battery now seems fine. This is day two since I drained it completely and again by now my battery would usually be down quarter to one half but it is still full half way through day. I know that ni-cad were worse about memory problem on charging but for some reason this recharging from completely being drained has put "new life" these two days now into battery.
Originally posted by SilvrDrgn Lithium Ion batteries don't suffer from the "memory" problem. So, I'm not sure why the complete drain of yours has had that effect. Weird.
That is what I too thought. but for two days now the battery is like it was new. So I am not sure what the complete drain did to the battery.

Yes you are right, but the difference here is when you keep topping up 'memory problem batteries' such as NiCad and, to an extent, 'NiMh', the memory problem is permanent. So even if you eventually do a few full drains and full recharges of those batteries, the life will always be reduced.
Li-Ions on the other hand are supposed to be topped up frequently - similar to Rechargable alkalines (though these should NEVER be fully drained) - but, as another topic here said, the device that measures how full the battery is becomes out of sync after many short top-ups, and simply stops the battery from charging before it actually reaches 100%, to prevent overcharging. This measurement device needs to be reset, and this is done by discharging, then fully recharging the battery.
I'm also not sure how often you'd need to this, but I try to (and usually happen to) do a full discharge then non-stop recharge every 2-3 weeks. I'd say leaving it in the charger for several hours after this will be 'trickle' charging it, and would probably help with the resetting of the measurement mechanism.
Battery life is not one of the 7135's strong points.
