I learned early on battery apps are hogs and counter productive. They take up space and tell you how quickly they're draining your battery. However over charging is bad for the battery, so a very cool app, very small and can be set to run only during charge and tell you when charge is complete is called Overcharged... only 64 kb and uses 4kb of data on my phone. I've set it to disable after unplugging but if you want the little number running up top you can set it that way. https://play.google.com/store/apps/details?id=com.dymsoft.com.overcharged&hl=en Spare Parts is another must have for this phone. We have no way of setting system font size, this app enable you to. Works well with the native messenger app (although I prefer to use an old version of "Go", no widget. When going through the menu, etc. You can see every thing on this screen and put down the reading glasses, sometimes. Only 320 kb, and 328 when running. Can load to SD but since it's working with the system and is so damn small I leave it on the phone. https://play.google.com/store/apps/details?id=com.droidgram.spareparts&hl=en OK, one more. Smart Keyboard Trial I can't believe what a great no bells and whistles app this is. It's smooth, aesthetically pleasing, my mike is right in there... just no emoji's and I could care less. I can make a smiley or a frowny face all by myself... see. That's enough for this baby boomer It's comparable to Go's keyboard without the extra's and is only 2.30mb and uses 44.0 kb. For a great keyboard, that's cool. I tried Gingerbread keyboard, this is way smaller and better. The English dictionary is another 0.90 mb and can go on the SD Card. These are all up to date versions, but there's some old good stuff out there. For instance my Go SMS Pro is version 4.52. Only 5.59 MB and 216kb of data. Works with mike and MMS. No widget but it notifies. Compare to the latest Go-Zilla Amazing it works, and really well. Even reads my texts aloud. It's amazing what you can safely find via third party. These two sites have never given me malware or any problems. I've used a few others but I'd only recommend these two. http://www.androiddrawer.com/ http://www.apkmirror.com/ At these sites I've gotten older, very functional versions of: Out of Milk 4.1.6 (SD) G Tasks (SD) Google Drive ver 22.214.171.124 10.57 MB and data varies. I'm at 468kb of data this app has to be on the phone. Voice Search 2.1.4 4.57mb and 8.00 kb (the current version isn't even compatible) I've even gotten smaller, older versions of play and play store although they'll just reinstall so I gave up on that one. To this novice memory and RAM are what runs or kills this phone. My stock Gz1 is currently has 129 MB of free RAM and 54 mb of IM. Also, stay with Pico TTS. On the last update it stopped working. I had no voice on Navigation and the google upgrade wasn't compatible. I had to download Svoxx crap, then I figured out during the update, the language pack wasn't included, but the app still was functional. It was hell finding it but all is backed up now and it works just fine with Google Navigation Yeah, my IM is getting low, but not to the point of a warning or a problem still...thanks Google Play for sucking I hope they slow down on expansion... or somebody out there can tell me how to partition my IM without root and move all the bloat and non-essentials to the card. Lastly, since us non rooters don't have a "disable" option, I suggest after charging clear the memory on all the app-crap you don't want running. You'll save boo-koo MB's. If ya' got something better or different puh-leese share!!!!! Hope this is helpful and some of you vets contribute what you might be using/know.
