New TiVo boxes generally come with the latest TE4 (TiVo Experience 4) user interface loaded onto them. You can sidegrade back to the earlier TE3 UI, which (at least currently, and hopefully forever into the future) does not do TiVo pre-roll ads nor the TiVo+ "service" (or list the latter in the TiVo Guide). How to Rollback Hydra from Roamio and Mini's v1
(works for the Bolt box as well, for all but the specifically-denominated Bolt OTA box). Many users prefer the TE3 UI.
Note that in sidegrading back to TE3, you lose the recordings on your box (but can transfer them to your PC first and then back again (to the extent not copy-protected) using pyTivo Desktop), voice control, the sleek TE4 interface, AutoSkip, and compatibility with the TiVo Mini WiFi Adapter. But you also gain a mostly ad-free experience (no pre-roll ads nor TiVo+ or its listing), the TiVo non-grid Guide, Suggestions that works, the ability to transfer shows between TiVo boxes from the boxes themselves, TiVo inter-box show transfers that don't glitch up (as often happens under TE4), and the PC -> TiVo box show transfer capability.
To easily lower your TiVo box ODT even further, passively: remove the cablecard compartment cover (!); and put the four corners of the box on risers (water bottle or other beverage container caps work great, and are cheap, lol). More actively, you also can put the TiVo box on a laptop/electronics fan cooling pad, or blow air at the box (small AC Infinity fans are great for this, and are well-liked here and inexpensive; available at Amazon.com).
The remote: I get 6+ months from alkaline batteries in my TiVo Slide Pro remote (note that it has buttons that will light up, and so uses more battery power), and significantly less from old-type lead batteries (got a whole bunch at a Black Friday sale, that I now need to use up, lol). Many people use rechargeables. Note that the System Info. screen that you got the box ODT info. from also lists a power-remaining percentage for your remote.
Hope this helps some--
